# What's new in USWDS 2.12.1
## Improvements and bug fixes

Version Library Beta 1 (2.14.0-beta.1)

July 09, 2021

This is the second beta of our codebase reorganization. While it's a follow-up to the [previous beta](https://github.com/uswds/uswds/releases/tag/v2.10.0-beta.0), it's completely independent of that beta and _does not_ use the Sass modules work from that earlier release. 

This beta is focussed on our internal organization and the library that helps us build the design system itself. **For all intents and purposes, this beta should be functionally equivalent to [USWDS 2.12.0](https://github.com/uswds/uswds/releases/tag/v2.12.0).** If you install this beta release, please use it as you would have used USWDS 2.12.0. Please let us know if you encounter any errors by adding an issue to this repo with `Library Beta 1` in the title.

Version 2.12.0

June 16, 2021

# What's new in USWDS 2.12.0

## New component
We have one new component in this release. Learn more about it on our website:

**[Pagination](https://designsystem.digital.gov/components/pagination):** Pagination is navigation for paginated content.

## New Spanish-language templates

We now have Spanish-language versions of our **404 template** and our **Authentication page templates**

## Other improvements and bug fixes

**Added more negative margin tokens to margin utilities.** Now you can use utilities like `margin-neg-4` and `margin-neg-5`. Thanks @mahoneycm! (https://github.com/uswds/uswds/pull/4212)

**Card's body exdent modifier now works as documented.** Now adding the `.usa-card__body--exdent` modifier will work as expected. Thanks @btwegmann! (https://github.com/uswds/uswds/pull/4165)

**Checkbox and radio buttons now include automatic accessible color.** Now checkbox and radio buttons will display in the proper accessible color, and adapt to the text, link, and background colors you set in your projects's settings. You can also declare a custom background color for checkbox and radio buttons with `$theme-input-background-color`. The selected tile color is now based on the accessible link color, and is not a custom setting.  (https://github.com/uswds/uswds/pull/4199)

We also added a new mixin to make it easier to scope custom checkbox and radio button colors: `checkbox-and-radio-colors($bg-color, $selected-color)`

It takes two color token inputs, `$bg-color` and `$selected-color`. Neither are required and will assume the values in settings if omitted. It returns all the code necessary to set checkbox and radio inputs for the desired scope.

For instance, if you wanted to change the color of all checkbox and radio elements within a `.checkbox-tests` container, you could do something like the following

.checkbox-tests {
  @include set-text-and-bg("green-80");
  @include checkbox-and-radio-colors("green-80", "green-warm-10v");
  padding: units(2);
  border-radius: radius("md");
**State color tokens available in default utilities.** Now you can use utilities like `text-primary-dark` in the default utility set. (https://github.com/uswds/uswds/pull/4198)

**The `success-dark` color token now looks better.** We updated the value of `success-dark` to be more vivid and look more like `success`. Thanks @maya! (https://github.com/uswds/uswds/pull/4183)

**Cleaner margins in radio tiles.** Now radio tiles have cleaner, more reliable styling for their margin. Thanks @maya! (https://github.com/uswds/uswds/pull/4181)

Version 2.11.2

April 28, 2021

# What's new in USWDS 2.11.2

## Bugfixes

**Checked radio buttons remain checked in disabled state.** Now the visual checked state of a checked checkbox does not change if that element is later disabled. (https://github.com/uswds/uswds/pull/4160)

**Fixed incorrect variable usage ($theme-site-max-width).** We updated our docs and settings to remove the `$theme-site-max-width` variable, which was in the docs and in the settings, but not in the code itself. In its place, use `$theme-grid-container-max-width`. `$theme-site-max-width` is marked for deprecation. (https://github.com/uswds/uswds-site/pull/1198)

**Added missing Summary Box package.** Now you can add a Summary Box package to your project with `packages/usa-summary-box`. (https://github.com/uswds/uswds/pull/4162) 

**Fixed unstyled button styling.** We updated and strengthened the styling of unstyled buttons to prevent any unwanted style leakage from conventional buttons, especially is used in conjunction with `usa-button--hover` and `usa-button--active` classes. Thanks @aduth! (https://github.com/uswds/uswds/pull/4077) 

**Fixed color of active parents in the side navigation.** We fixed a regression where the parent items in the side navigation no longer received the `primary` color. Thanks @asarazor! (https://github.com/uswds/uswds/pull/4163)

⚠️ **Fixed the size of some of our icons.** The view box on some or our icons was 20px instead of 24px. We updated these icons to use the proper view box. This may result in small changes to the display of icons, but will result in a more consistent placement and appearance across all icons in our icon set. (https://github.com/uswds/uswds/pull/4139)

⚠️ **Swapped thumb icons in our sprite for consistency.** We replaced `thumb_down_off_alt` with `thumb_down_off` in our icon sprite for consistency with its `thumb_up` pair. (https://github.com/uswds/uswds/pull/4139) 

⚠️ **Removed duplicate eye icon.** Removes `remove_red_eye` icon from `usa-icons` and sprite. Use of `visibility` instead. (https://github.com/uswds/uswds/pull/4139)

Version 2.11.0

March 17, 2021

# What's new in USWDS 2.11.0

## New components
We have three new components in this release. Learn more about them on our website:

- **[Icon list](https://designsystem.digital.gov/components/icon-list):** An icon list reinforces the meaning and visibility of individual list items with a leading icon.
- **[Modal](https://designsystem.digital.gov/components/modal):** A modal disables page content and focuses the user’s attention on a single task or message.
- **[Input prefix or suffix](https://designsystem.digital.gov/components/input-prefix-suffix):** Use input prefixes and suffixes to show symbols or abbreviations that help users enter the right type of information in a form’s text input.

## Updated components

We have two updated components in this release. Learn more about each of them on our website:

- **[Sortable table](https://designsystem.digital.gov/components/table/#sortable-table-rows):** A sorted column changes the row ordering based on alphabetical or numeric cell values.
- **[Links](https://designsystem.digital.gov/components/link):** We updated and improved our guidance around links. Notably, we no longer suggest using the external link icon, as it is often interpreted as `share` or `open in a new tab`. Instead, we recommend adding a link destination into the text of the link if you need to be clear where the link points. We've also expanded our guidance around linking to documents.

## New templates

We have one new template in this release. Learn more about it on our website:

- **[404 page](https://designsystem.digital.gov/templates/404-page/):** A 404 page informs users that a requested page doesn’t exist.

## Other improvements and bug fixes

**Fixed tooltip positioning.** We fixed an issue that prevented some longer tooltips in some positions to display incorrectly. (https://github.com/uswds/uswds/pull/4062)

**Using a custom font without a custom font stack now get a default font stack.** We fixed as bug where setting a custom font without setting a custom font stack resulted in no font stack at all. Now custom fonts will get a default stack appropriate to it's type (`sans`, `serif`, or `mono`). (https://github.com/uswds/uswds/pull/4084)

**Now you can use a custom prefix separator.** Some systems don't parse the `:` separator character in the default USWDS responsive and state prefixes like `tablet:margin-x-2`. Now you can set the value of `$theme-prefix-separator` to output any character or string between the prefix and the main class. (https://github.com/uswds/uswds/pull/4085)

Note that the default needs two `\` characters to properly output the escaped `:` character in the final CSS.

$theme-prefix-separator: "\\:",
ex: .tablet\:margin-x-2
     <div class="tablet:margin-x-2">

$theme-prefix-separator: "--",
ex: .tablet--margin-x-2
     <div class="tablet--margin-x-2">


**Fixed character display in checkboxes and radio buttons.** The  character can show up next to checkboxes and radio buttons where a non-breaking space should be when `<meta charset="utf-8">` isn't set properly. Now it will display properly regardless of character encoding. Thanks @andycochran! (https://github.com/uswds/uswds/pull/4080)

**Provide better support for color icons that adapt to theme settings.** Now the color of the alert icon will update automatically to adapt to the alert background, or to the color of the alert text. (https://github.com/uswds/uswds/pull/4079)

**Updated the banner to use the new icon set.**

## Bugfixes and updates
**Fixed `SVG4Everybody` compatibility.** Now USWDS javascript will compile properly with Babel. Now you should be able to use `uswds.js` or `uswds.min.js` in a React app without any problems. Thanks @aduth!

**Fixed a flash of unstyled content in extended header megamenu.** Now there won't be a flash of megamenu content while the USWDS javascript loads. (Note: This requires `uswds-init`.)

**Added more white icon variants.**  Added white icon variants for `add`, `remove`, and `expand_more` so teams can have accessible icon color combinations on dark backgrounds, especially in the accordion and the top navigation.

**More consistently use theme text and link colors across components.** Improved our use of `$theme-text-` and `$theme-link-` color settings in components and variants like `usa-dark-background` and `usa-section--dark`.

Version 2.10.1

February 19, 2021

# What’s new in USWDS 2.10.1

## Bugfixes and updates
**Fix automatic accessible color picker:** Now the accessible color picker will properly pick the correct text color from a given background color. It will also throw warnings instead of errors if accessible combinations aren't found. (#3906 and #3926)

New or ⚠️ changed setting | Default | Description
--- | --- | ---
$theme-body-background-color | `"white"` | Background for the page body
$theme-text-color | `"ink"` | Page text color

$theme-alert-link-reverse-color | `default` (uses whatever is set for `$theme-link-reverse-color`) | Link color for dark-background alerts
⚠️ $theme-breadcrumb-background-color | `default` (uses whatever is set for `$theme-body-background-color`) | Background color for the breadcrumb
$theme-identifier-primary-link-color | `default` (system picks between `$theme-alert-link-color` and `$theme-alert-link-reverse-color` depending on the background color) | Color of the links in the identifier masthead

**Allows `svg4everybody` polyfill to compile properly in React and Vue:** Now React and Vue applications won't crash with a TypeError caused by `svgforeverybody`. (https://github.com/uswds/uswds/issues/3909)

**Properly give an accessible name to the combobox:** Now the combobox will have an accessible name as long as the label's `for` attribute matches the id of the `input.usa-combo-box` or `input.usa-time-picker`. (https://github.com/uswds/uswds/issues/3900)

**Fix styling in collection calendars:** Removes a thin white line which could appear at the top of calendars in collection items. (https://github.com/uswds/uswds/pull/3917)

**Fix a radio/checkbox focus outline bug on Firefox.** Removes unwanted text indent from checkbox and radio input, which was causing the focus outline to be improperly sized on Firefox. (https://github.com/uswds/uswds/issues/3916)

**Utilize `$theme-alert-icon-size` variable for setting the alert icon size:** Now the setting works as expected. Thanks @sawyerh! (https://github.com/uswds/uswds/pull/3942) 

> ⚠️ NOTE: This changes the value of the `$theme-alert-icon-size` default to `5` from `4`.

**Adds an instagram social icon to our default footer.** (https://github.com/uswds/uswds/pull/3948)

**Updates all icons used by components to the new icon set.** (https://github.com/uswds/uswds/pull/3992)

**Fixes left padding for anchor links in the sidenav.** Thanks @fsierra! (https://github.com/uswds/uswds/issues/3944)

**Fixes the import path for the `usa-icons` package.** Thanks @jennyychaa! (https://github.com/uswds/uswds/issues/3954)

**Fixes a secondary nav display bug in the header in Safari:** Now the search component and the secondary nav display and resize properly in Safari. Thanks @akanelson! (https://github.com/uswds/uswds/issues/3805)

⚠️ **Use proper semantic markup for footer title:** Now we're using a `p` instead of an `h3` for `usa-footer__logo-heading` since the name of the project or agency is hot a heading in this context.

**Properly wrap the wrapped breadcrumb on Safari:** Now the `usa-breadcrumb--wrap` breadcrumb variant will wrap properly on Safari, instead of overflowing. (https://github.com/uswds/uswds/issues/3997)

**Update project's version of Node to the most current LTS (14.15.4).**

## No more banner flash: The USWDS initializer script

USWDS 2.10.0 adds a small (under 1 KB minified) initialization script (`uswds-init.min.js`) to the package. When included in the `<head>` — either by reference or inline — this script prevents the banner from flashing its content on page load and shifting content (https://github.com/uswds/uswds/issues/3092).

**Note: This only prevents flashing when you use CSS generated from USWDS 2.10.0 or later.**

### What it does


- It adds a `.usa-js-loading` class to the `<html>` element as the USWDS JS library is loading.

In more detail:

- If JavaScript is present, it adds a `.usa-js-loading` class to the `<html>` element before the `body` renders.
- If the USWDS JS library loads, it removes the `.usa-js-loading` class.
- If the USWDS JS library does not load in a timeout period, it removes the `.usa-js-loading` class.

Since USWDS components are meant to make their content available even if our JS does not load, their visibility of any toggle-able content defaults to visible and the JS is responsible for hiding it. This resulted in a flash of "hidden" content between when the page renders and the JS loads.

This initialization script allows us to visually hide "hidden" content at page render by hooking those styles to the `.usa-js-loading` class. When the USWDS JS loads, the JavaScript is responsible for hiding/showing interactive content as usual and the class hook is removed. If the USWDS JS does not load, `uswds-init` removes the `.usa-ls-loading` class and the content will revert to visible. If there is no JS present at all, `uswds-init` will not load and the content will be visible at page render.

### Using the initializer

1. Copy `uswds-init-min.js` out of the USWDS package an into your project directory.
2. Reference the script in the document `<head>` or include the entire script inline.

#### Include by reference

<!DOCTYPE html>
    <script src="assets/uswds/js/uswds-init.min.js"></script>
    <link rel="stylesheet" href="assets/uswds/css/uswds.min.css" />
    <script src="assets/uswds/js/uswds.min.js"></script>

#### Include inline

<!DOCTYPE html>
      const docElem=window.document.documentElement,loadingClass="usa-js-loading";function addLoadingClass(){docElem.className+=` ${loadingClass}`}function revertClass(){docElem.className=docElem.className.replace(loadingClass,"")}if("querySelector"in window.document&&"addEventListener"in window){addLoadingClass();const e=setTimeout(revertClass,8e3);let s=100;const n=()=>{setTimeout(()=>{s+=1,"undefined"!=typeof uswdsPresent?(clearTimeout(e),setTimeout(revertClass,100)):s>0&&n()},100)};n()}
    <link rel="stylesheet" href="assets/uswds/css/uswds.min.css" />
    <script src="assets/uswds/js/uswds.min.js"></script>

## Other improvements and bug fixes

**Improved non-autoprefixed state of colored icons.** When you see a USWDS icon that appears as a rectangle instead of its proper shape, this is because some USWDS colored icons require Autoprefixer to display properly. Now the non-Autoprefixer icon will appear as a black icon instead of as a rectangle. All projects should still [use Autoprefixer when compiling their stylesheets](https://designsystem.digital.gov/documentation/developers/#sass-compilation-requirements). Thanks @aduth! (https://github.com/uswds/uswds/pull/3860)

**Improved the accessibility of decorative images in the Banner.** We modified the Banner to properly mark up SVG files used as decorative images. Now all decorative images are hidden from screen readers, and all SVGs are more resilient to browser bugs. See the Banner page for the complete, correct markup, and see the pull request for more context on the changes. (https://github.com/uswds/uswds/pull/3892)

> :warning: This requires a manual change on any site that uses the Banner.
> - Use `alt=""` for any decorative `<img>` element
> - Use `role="img"` for `<img>` elements with an SVG source
> - Use `aria-hidden="true"` for decorative `<img>` elements with an SVG source
> - Use `role="img"` and `focusable="false"` for `<svg>` elements meant to be images (ie don't contain text/data)
> - Use `aria-hidden="true"` for decorative `<svg>` elements
> - Use `aria-label="[accessible name]"` or `aria-labelledby="[id list]"` for `<svg>` elements that convey information and need an accessible description

**Created a Spanish version of the Search component.** We recommend using "Buscar" in Spanish-language version of Search. See the [Search guidance page](https://designsystem.digital.gov/components/search/) for more information. Thanks @lggsa! (https://github.com/uswds/uswds/pull/3861)

**Updated the Spanish USAGov link in the identifier.** The Spanish-language USAGov link in the identifier should read `Visite USAGov en Español` (https://github.com/uswds/uswds/pull/3863)

> :warning: This requires a manual change on any site that uses the Spanish-language identifier.
> `Visite USA.gov en Español` → `Visite USAGov en Español`

**Support custom bold font weight.** Now `$theme-font-weight-bold` will change the theme bold font weight as expected. Thanks @sawyerh! (https://github.com/uswds/uswds/pull/3811)

**Allow proper drag/drop on File input component.** Now drag and drop will accept or reject files as expected when using a File input set to accept multiple extensions. Thanks @ConnorDY! (https://github.com/uswds/uswds/pull/3851)

**Enable proper hover styles on visited links.** Now visited links have a visible hover state. Thanks @astiefvater! (https://github.com/uswds/uswds/pull/3868)

**Enable and disable File Input programmatically.** Now developers can set the status of the File Input component dynamically. Thanks @ConnorDY! (https://github.com/uswds/uswds/pull/3760)

**Better support for buttons with multiple variants.** We fixed a display bug with visited inverse unstyled buttons. Button styling is more reliable with different combinations of variants. Thanks @andycochran! (https://github.com/uswds/uswds/pull/3846)

**Support buttons in side navigation.** Now any anchor link button in a Side Navigation component hill have expected display. Thanks @ajware-uscis! (https://github.com/uswds/uswds/pull/3839)

**Allow custom hex colors as File Input disabled color.** We fixed a bug that prevented a custom hex value for `disabled-light` from working in the File Input component. Thanks @aduth! https://github.com/uswds/uswds/pull/3762

**Improved font display in the Identifier.** We're now using normal weight text in the Identifier domain text instead of light text for more consistent appearance. (https://github.com/uswds/uswds/pull/3740)

**Improved breadcrumb padding.** Fixes a bug that could make some values of `$theme-focus-width` incompatible with the Breadcrumb. (https://github.com/uswds/uswds/pull/3737)

Version 2.10.0 Beta 0

September 28, 2020

# About 2.10.0 Beta 0
This release is a port of USWDS 2.9.0 to the most recent Sass syntax, the [Sass Module System](https://sass-lang.com/blog/the-module-system-is-launched) [SaMS]. This new syntax allows a couple specific improvements to the design system:

- **Namespacing: It's more compatible with other Sass frameworks.** SaMS offers optional custom namespace for any USWDS variables, mixins, and functions, assuring that there are never any collisions between similarly named functionality across libraries (like two functions called `color()`).
- **Subsetting: It loads only what you need.** SaMS makes it simpler to subset the design system to include only the components you need, with no redundant imports and minimal unused rules.

There's a lot of reorganization under the hood to reflect our focus on modularity (and more to come as the beta integrates a new library structure) but this reorganization should have minimal impact on how you load and use the design system. Just how you load the new code depends on how extensively you want to use namespacing or subsetting

**⚠️ Note:** Throughout this guidance, we'll be referring to the **Sass entry point**, your project's `.scss` file that points the compiler to the files it needs to compile the design system CSS. If this is an unfamiliar concept we discuss it in greater detail in our [USWDS Fundamentals and quickstart guide](https://designsystem.digital.gov/documentation/fundamentals/).

## Requirements
This currently requires a compile path that uses Dart Sass.

- **Example:** Use Gulp with `gulp-sass` and `sass`,  and `sass.compiler = require('sass');` set in the gulpfile.
- **Example:** Use `uswds-gulp`

**⚠️ Note: Many compilers based on libsass or other libraries do not fulfill these requirements.** Notably, this includes the native compiler built into Jekyll (`jekyll-sass-converter`), `node-sass`, and likely others. If this beta package doesn't work for you, it's probably due to this requirement. We're working to see what kinds of compile workarounds are possible in the most common environments. Your feedback and experimentation during the beta process will help us evaluate the practicality of integrating SaMS into USWDS.

## Implementation
The most important thing to remember is that you can't use `@import` in the same file that you use a new SaMS rule like `@use` or `@forward`. Each individual file can play by its own rules, but you can't mix old and new rules in any individual file.  In effect, mixed implementations need to create a SaMS entry point imported from the primary Sass entry point. In the examples below, we've named that SaMS entry point `theme-modules`.

**Note:** In mixed implementations, the SaMS entry point must `@forward` either `uswds` or a USWDS package (like `packages/uswds-core`) to apply the imported settings upstream of using  `@use` to load mixins and functions into a stylesheet.

Additionally, each example in this section assumes that you're keeping all your project sass files in a single directory in the project root. Your project can have a different structure, you'd just have to adjust the load paths to fit.

### Simple: Use USWDS as in earlier versions
You should be able to use this beta release without making any changes to your Sass entry point. Conventional `@import` rules will work with this release just as they did with earlier USWDS releases.

// styles.scss
@import "uswds-theme-general";
@import "uswds-theme-typography";
@import "uswds-theme-spacing";
@import "uswds-theme-color";
@import "uswds-theme-utilities";
@import "uswds-theme-components";
@import "../node_modules/uswds/dist/uswds";
@import "uswds-theme-custom-styles";

### Intermediate: Package subsetting
Subsetting means loading only the packages and styles you need for your project. Each USWDS component has a package (typically the same as its class name, `usa-[component]`). There are also a few special packages:

package | description
--- | ---
**uswds-components** | all components
**uswds-core** | only the USWDS core internals — tokens, functions, and mixins
**uswds-elements** | limited styling for unclassed html elements
**uswds-fonts** | the font-face generator
**uswds-form-controls** | all form controls
**uswds-form-templates** | all form templates
**uswds-global** | core, elements, and helpers + normalize
**uswds-helpers** | non-utility helper classes, like usa-sr-only and usa-focus
**uswds-layout-grid** | the layout grid classes
**uswds-typography** | styles related to text and headings
**uswds-utilities** | utility classes
**uswds-validation** | components related to form validation

Find packages in the `dist/packages` directory in the USWDS npm package.
// styles.scss
@import "uswds-theme-general";
@import "uswds-theme-typography";
@import "uswds-theme-spacing";
@import "uswds-theme-color";
@import "uswds-theme-utilities";
@import "uswds-theme-components";
@import "theme-modules";
@import "uswds-theme-custom-styles";

// theme-modules.scss

@forward "../node_modules/uswds/dist/packages/usa-banner";
@forward "../node_modules/uswds/dist/packages/usa-identifier";
@forward "../node_modules/uswds/dist/packages/usa-button";
@forward "../node_modules/uswds/dist/packages/uswds-form-controls";

### Intermediate: Namespacing
Namespacing adds a custom prefix to variables, mixins, and functions loaded with the @use rule. Use custom namespacing to prevent collisions between similarly-named functionality in multiple libraries.

// styles.scss
@import "uswds-theme-general";
@import "uswds-theme-typography";
@import "uswds-theme-spacing";
@import "uswds-theme-color";
@import "uswds-theme-utilities";
@import "uswds-theme-components";
@import "theme-modules";

// theme-modules.scss
@forward "../node_modules/uswds/dist/uswds";
@forward "theme-custom-styles";

// theme-custom-styles.scss
@use "../node_modules/uswds/dist/uswds" as usa;
.foo {
  @include usa.u-margin-x(1)
  color: usa.color("primary-vivid");

### Intermediate: Package subsetting and custom namespace
You can also do both subsetting and namespacing with a hybrid implementation.

// styles.scss
@import "uswds-theme-general";
@import "uswds-theme-typography";
@import "uswds-theme-spacing";
@import "uswds-theme-color";
@import "uswds-theme-utilities";
@import "uswds-theme-components";
@import "theme-modules";

In the SaMS entry point, include both packages and custom styles.
// theme-modules.scss
@forward "theme-packages";
@forward "theme-custom-styles";

For packages, include individual component packages…
// theme-packages.scss
@forward "../node_modules/uswds/dist/packages/usa-banner";
@forward "../node_modules/uswds/dist/packages/usa-identifier";
@forward "../node_modules/uswds/dist/packages/usa-button";
@forward "../node_modules/uswds/dist/packages/uswds-form-controls";

…or include just the USWDS core internals
// theme-packages.scss
@forward "../node_modules/uswds/dist/packages/uswds-core";

Load custom styles as before, using the `uswds-core` package with the desired namespace.
// theme-custom-styles.scss
// Use packages/uswds-core to include core internals only
@use "../node_modules/uswds/dist/packages/uswds-core" as usa;
.foo {
  @include usa.u-margin-x(1)
  color: usa.color("primary-vivid");

### Advanced: Use native SaMS instead of imports
The big change in using a SaMS-only implementation is that your packages forward needs to include all changed settings as a single map object passed as its config.
// styles.scss
@forward "theme-modules--packages" with (
  $theme-show-notifications: false,
  $theme-color-primary-vivid: "orange-20v",
@forward "theme-modules--custom";

Include any packages or USWDS core internals, as before.
// theme-modules--packages.scss

@forward "../node_modules/uswds/dist/packages/usa-banner";
@forward "../node_modules/uswds/dist/packages/usa-identifier";
@forward "../node_modules/uswds/dist/packages/usa-button";
@forward "../node_modules/uswds/dist/packages/uswds-form-controls";
// or
@forward "../node_modules/uswds/dist/packages/uswds-core";

Include any packages or USWDS core internals, as before.
// theme-modules--custom.scss
@use "../node_modules/uswds/dist/packages/uswds-core" as usa;
@forward "custom-styles-one";
@forward "custom-styles-two";

Each custom styles file needs to `@use` the `uswds-core` package.
// custom-styles-one.scss
@use "../node_modules/uswds/dist/packages/uswds-core" as usa;
.foo {
  @include usa.u-margin-x(1)
  color: usa.color("primary-vivid");

Stylesheets can reference other sheets if they `@use` that stylesheet explicitly.
// custom-styles-two.scss
@use "../node_modules/uswds/dist/packages/uswds-core" as *;
@use "custom-styles-one" as *;
.bar {
  @extend .foo;
  @include u-margin-y(1)
  color: color("secondary-vivid");

## What we expect from a beta tester
- Add the beta package to your project with the simple implementation and see if it compiles as expected
- Try some of the intermediate implementations: subsetting or namespacing
- File any questions of bugs in the `uswds` repo
  - Use the `beta` label
  - Be as descriptive as possible about how to reproduce a bug
  - Attach any setup information (beta version, compiler, framework, os, etc)
- Ask questions in the` #uswds-public` Slack

Version 2.9.0

September 22, 2020

# What’s new in USWDS 2.9.0

## New components
We have three new components in this release. Learn more about each of them on our website:

- **[Identifier](https://designsystem.digital.gov/components/identifier):** The identifier communicates a site's parent agency and displays agency links required by federal laws and policies.
- **[Step indicator](https://designsystem.digital.gov/components/step-indicator):** A step indicator updates users on their progress through a multi-step process.
- **[Time picker](https://designsystem.digital.gov/components/form-controls/#time-picker):** A time picker helps users select a specific time.

## Improvements and bug fixes
**Added flex-align-self utilities.** Now you can apply the `align-self` property to an element using flex-align-self utilities. The align-self rule is conceptually similar to flex-align, except `align-self` applies at the flex child level instead of the flex parent level. Thanks @taylorsolomon! (https://github.com/uswds/uswds/pull/3588)

- **flex-align-self-start:** align element at the start of the parent's cross axis
- **flex-align-self-middle:** align element in the middle of the parent's cross axis
- **flex-align-self-end:** align element at the end of the parent's cross axis
- **flex-align-self-stretch:** stretch across the full extent of the parent's cross axis

**Added an accent-warm button variant.** Now you can use `accent-warm` buttons with `usa-button--accent-warm`. (https://github.com/uswds/uswds/pull/3623)

**Generating SHA-256 hashes for our ZIP releases.** We're now generating a SHA-256 hash with the ZIP download and documenting this hash in our repo and on our website. Anyone can now check the integrity of a release ZIP file by generating a hash for their local file and comparing it to the hash we post in the github repo and on our site. (https://github.com/uswds/uswds/pull/3577)

**Proper disabled radio buttons.** We fixed the display of disabled radio buttons so both the label and radio button both appear disabled. Thanks @brayfe! (https://github.com/uswds/uswds/pull/3613)

**Proper secondary button active state.** We fixed the active state of the secondary color button. Thanks @maya! (https://github.com/uswds/uswds/pull/3615)

**Improved styling of lists inside alerts.** We improved the styling of simple and complex lists inside alerts. (https://github.com/uswds/uswds/pull/3507)

**More consistent styling of legend element.** We improved the styling of the  usa-legend element to better match other labels in a form, and improved the spacing between legends and both radio buttons and checkboxes. We added a `usa-label--large` variant to mimic the older, less consistent styling for backward compatibility. (https://github.com/uswds/uswds/pull/3465)

Version 2.8.1

August 17, 2020

# What's new in USWDS 2.8.1
## Improvements and bug fixes
**Allow custom colors in link calculations.** Now projects that use custom hex colors in their theme colors can generate CSS without errors. For standard USWDS tokens, the link color calculator generates a hover color one system grade level above or below the link color in the same vivid state. Now the calculator does the same with custom hex theme tokens, except using the theme color grades. (https://github.com/uswds/uswds/issues/3568)

**Added a max-width setting to the footer.** We added a `$theme-footer-max-width` setting to constrain the footer content, similar to what we already provide for the banner. (https://github.com/uswds/uswds/issues/3532)

**Improved date picker focus state.** We fixed a bug that cut off part of the date picker's date focus ring in IE11. (https://github.com/uswds/uswds/issues/3578)

**Improved combo box resizing.** We fixed a display bug with the combo box where custom combo box sizing wasn't reflected in its input. Thanks @fafnirical! (https://github.com/uswds/uswds/pull/3583)

**Improved combo box dropdown overlapping.** We fixed a display bug with the combo box where neighboring combo box UI elements could overlap with the combo box dropdown. Thanks @Pharmasolin! (https://github.com/uswds/uswds/pull/3572)

# What's new in USWDS 2.8.0

## New components
We're excited to release a new batch of components. Learn more about each of them on our website:

- **[Breadcrumb](https://designsystem.digital.gov/components/breadcrumb/):** Breadcrumbs provide secondary navigation to help users understand where they are in a website.
- **[Date picker](https://designsystem.digital.gov/components/form-controls/#date-picker):** A date picker helps users select a single date.
- **[Date range picker](https://designsystem.digital.gov/components/form-controls/#date-range-picker):** A date range picker helps users select a range between two dates.
- **[File input](https://designsystem.digital.gov/components/form-controls/#file-input):** File input allows users to attach one or multiple files.
- **[Tooltip](https://designsystem.digital.gov/components/tooltip/):** A tooltip is a short descriptive message that appears when a user hovers or focuses on an element.

## Updates to the banner
We've made some important [updates to the banner text](https://designsystem.digital.gov/components/banner/). Our new banner text incorporates feedback we've received over the last year or so, and incorporates a few key enhancements:

- [Emphasize that trustworthiness is a combination of an official TLD and a secure HTTPS connection](https://github.com/uswds/uswds/pull/3373)
- [Stay up to date with the different ways to determine HTTPS usage in your browser](https://github.com/uswds/uswds/issues/3281)
- Provide official language support for other languages, starting with Spanish (with the help of the USAGov en Español team)
- Focus the message by using TLD-specific copy for .mil sites

Teams should work to update this banner text as soon as possible. Consistency improves the reliability, trustworthiness, and awareness of this important component. Thanks @h-m-f-t, @konklone, @wslack, @lggsa, and @leilanimartinez!

These banner updates also include **better settings support** for the banner, including support for custom banner background and link colors, and **improved readability at wide display widths**. 

⚠️ The banner code requires Autoprefixer to work properly. See https://designsystem.digital.gov/documentation/developers/#sass-compilation-requirements

Version 2.7.1

June 17, 2020

# What's new in USWDS 2.7.1

## Improvements to combo box
We listened to your feedback and made a number of improvements and upgrades to our new combo box.

**Show proper focus in combo box.** Hover and keyboard events transfer focus to individual options, and now the styling reflects that. (https://github.com/uswds/uswds/pull/3493)

**Disabled combo boxes remain disabled after enhancement.** The `disabled` attribute now correctly results in a disabled combo box. (https://github.com/uswds/uswds/pull/3484)

**Use data attributes to set combo box placeholder and default.** We now use data attributes to set the default value (`data-default-value`) and placeholder (`data-placeholder`). (https://github.com/uswds/uswds/pull/3486)

**Improved combo box interactions.** Allows list toggling with the toggle button, and adds a "clear input" button to start a subsequent combo box interaction. Makes a number of additional improvement to how the combo box handles changes and new selections. (https://github.com/uswds/uswds/pull/3505)

**Combo box now triggers a change event on `input` and `select` change.** Now we fire proper change events on the `<select>`. Thanks @ConnorDY! (https://github.com/uswds/uswds/pull/3487)

**We fixed the punctuation on the default combo box.** Now there's no more colon, consistent with other input guidance. (https://github.com/uswds/uswds/pull/3473)

**The combo box scrollbar works.** Now you can scroll a combo box with the scrollbar! (https://github.com/uswds/uswds/pull/3483)

## Other improvements and bug fixes
**Improved the reliability and cross-browser compatibility of our flexbox usage.** We rebuilt how the design system outputs its flex utilities and mixins so any flex-based rules display properly and as expected in browsers from IE11 up. (https://github.com/uswds/uswds/pull/3480)

**Improve display of media block.** This element now uses flexbox instead of floats, so text in a media block is no longer cut occasionally cut off at the end of a line in IE11. Thanks @maya! (https://github.com/uswds/uswds/pull/3453)

**Mobile menus can now be closed with the `esc` key in IE11.** Now, the escape key will properly close mobile menus in IE11. Thanks @joncasey! (https://github.com/uswds/uswds/pull/3468)

**Improved our Autoprefixer and Browserslist settings.** We added `not dead` to our Autoprefixer settings and now use a `.browserslistrc` file for these options. This gets us more in line with Autoprefixer and Browserslist best practices. Thanks @ai! (https://github.com/uswds/uswds/pull/3458)

**Fixed IE11 display issue in mobile nav.** Now nav elements display as expected at mobile width on IE11. (https://github.com/uswds/uswds/pull/3470)

**Fixed a potential Unhandled rejection Parsing error in the codebase.** Thanks @hursey013! (https://github.com/uswds/uswds/pull/3497)

**Added `role="img"` to SVG images.** Thanks @sslawrence521! (https://github.com/uswds/uswds/pull/3501)

**Fixed spacing in nested lists.** Now nested lists will have proper formatting and spacing regardless of the value of `$theme-global-content-styles`. Thanks @jonraedeke! (https://github.com/uswds/uswds/pull/3495)

**Fixed a color contrast issue in our `accent-cool` button.** Now all our buttons have the proper AA contrast between the button background and the button text. And we've built our code to be smart enough to adjust the text color to adapt to any project's theme color definitions. (https://github.com/uswds/uswds/pull/3492)

To better provide resilience in our color contrast, we're introducing two new mixins to help provide a more resilient codebase:

@include set-text-from-bg( 

@include set-text-and-bg( 

preferred-text-color default: "white"
fallback-text-color default: "ink"
WCAG-level default: "AA"


For a given `background-color` token, each mixin checks contrast against the `preferred-text-color` and uses that as the text color unless it doesn't pass the contrast requirements of the `WCAG-level`. Then it checks `fallback-text-color` and uses that color unless it doesn't meet contrast requirements, in which case it returns an error.

**set-text-from-bg**(): Sets only the text color.
**set-text-and-bg**(): Sets both the background color and the text color.

Version 2.7.0

May 11, 2020

# What's new in USWDS 2.7.0

## New components
Read more about these components on our website, but we're excited to start releasing the first of a number of new design system components planned for 2020:

- **Button group:** Use button groups to collect similar or related actions.
- **Card:** Cards contain content and actions about a single subject.
- **Character count:** Character count helps users know how much text they can enter when there is a limit on the number of characters.
- **Combo box:** A combo box helps users select an item from a large list of options.

## Improvements and bug fixes
**Improved mobile experience for numeric fields.** We updated our guidance and code for numeric fields to follow the lead of gov.uk's recent [guidance](https://design-system.service.gov.uk/components/text-input/#numbers) and [research](https://technology.blog.gov.uk/2020/02/24/why-the-gov-uk-design-system-team-changed-the-input-type-for-numbers/). This updates those fields to use `text` rather than `number` inputs with an `inputmode` of `numeric`. (https://github.com/uswds/uswds/pull/3392)

**Fixed color token errors.** We made some mistakes adding the new color tokens into the system in `2.6.0`. Now the values of `Indigo cool 60v`, `Indigo cool 70v`, and `Indigo cool 80v` fall within our grade guidance, and match both the documentation and the design assets. (https://github.com/uswds/uswds/pull/3455)

**Improved styling of Skipnav component.** Now the Skipnav includes proper link formatting. (https://github.com/uswds/uswds/pull/3393)

**Improved display of the `Here's how you know` link in the gov banner.** Now there's no distracting change to the length of the underline on hover. (https://github.com/uswds/uswds/pull/3427)

**Assure external link icon wraps properly.** Now the external link icon won't get stranded as a widow on a new line. It will break to a new line only with its link text. (https://github.com/uswds/uswds/pull/3428)

**Provide a more reliable treatment for dropdown menus.** Now dropdown menus won't get cut off if they come too close to the header boundary (https://github.com/uswds/uswds/pull/3438) and menus with `usa-current` nav elements won't display an unnecessary underline at desktop widths (https://github.com/uswds/uswds/pull/3434).

Version 2.6.0

March 18, 2020

**Use more consistent search markup.** We made the markup of `usa-search` more consistent and assured that the styling worked properly regardless of what version of the markup you're using. This is not as breaking change, but we recommend updating your search markup to the most current version. (https://github.com/uswds/uswds/pull/3327)

**Utilities output specified pseudoclasses correctly.** We fixed a bug that prevented the utilities from outputting certain pseudoclass prefixes like `active:`, `visited:` and `focus:`. (https://github.com/uswds/uswds/pull/3346) Thanks @greenca6!

**Improved letterspacing function.** This fixes a bug that caused the letterspacing functions to output the wrong value for `1`. Now the utilities and the functions output the same values. (https://github.com/uswds/uswds/pull/3343) Thanks @maya!

**Provide complete vivid color families.** Now each color family has vivid grades from `5`-`80`. Changing families in settings is more reliable and will no longer result in pointing to false values. Each new color is normalized to our new color grade luminance range guidance. (https://github.com/uswds/uswds/pull/3351) Thanks @jlarmstrongiv!

**Provide a more reliable and consistent color system.** Each new color is normalized to our new color grade luminance range guidance, so all magic number combinations will work as promised. (https://github.com/uswds/uswds/pull/3351) Thanks @darekkay!

Version 2.5.1

March 03, 2020

**Removed media query sorting.** CSSO's `forceMediaMerge` wasn't exporting media queries in the expected order, so we're disabling it for more reliable CSS output. While both the minified and unminified CSS files are modestly larger as a result: `268 KB` unsorted vs. `259 KB` sorted, our testing indicates that once the files are compressed server side with gzip, the unsorted CSS is actually smaller: `36 KB` unsorted and gzipped vs. `38 KB` sorted and gzipped. As a result, we recommend that teams do not use media query sorting at this time.

**Note:** This release also temporarily removes the best practice tests from our aXe testing until we can reinstate these tests as warnings rather than errors (#3333). This aXe change should come in the next minor version this month (`2.6.0`).

Version 2.5.0

February 14, 2020

# What's new in USWDS 2.5.0

:warning: **Improved component accessibility and testing.** We upgraded our accessibility testing with aXe from `2.6.1` to `3.4.1` and improved the accessibility of our markup in the process. This introduces minor changes to the markup of 5 components and our documentation template — you should update your markup, but existing markup will not break:

- **banner:** is now a `<section>` instead of a `<div>` with the ARIA label `Official government website`
- **footer:** nav includes the ARIA label of `Footer navigation`
- **graphic-list:** uses `h2` as a heading default instead of `h3`
- **hero:** includes the ARIA label of `Introduction`
- **search:** the search form is given the ARIA role of `search`
- **documentation template:** includes only the main content in the `<main>` element. The nav is no longer treated as an `<aside>`

PR: https://github.com/uswds/uswds/pull/3280

**Allow non-token values in state color settings.** Now state tokens (like `"warning"`) can accept non-token colors, just as we introduced for theme colors in `2.4.0`. Teams using non-token values can now keep colors consistent between theme and state. Using non-token values will throw a warning in the compile process, but this, like all compile warnings, can be disabled by setting `$theme-show-compile-warnings: false`. Thanks @sawyerh! https://github.com/uswds/uswds/pull/3289

**Updated to the canonical Sass compiler.** We're now using Dart Sass to compile the system Sass. Dart Sass is the canonical Sass compiler, so using it will keep us at feature parity and help prevent inadvertent inconsistencies. https://github.com/uswds/uswds/pull/3304

**Output utility classes in proper order without media query sorting.** We no longer require media query sorting for proper utility class output. We no longer use a dedicated media query sorter in our dependencies, and do all our optimization with [csso](https://github.com/css/csso) (deprecating cssnano). https://github.com/uswds/uswds/pull/3308

**Improved performance.** We've improved the time it takes to compile the design system and its overall file size:

| version | build:sass | gulp sass | unminified | minified
| --- | --- | --- | --- | ---
| 2.4.0 | 14s | 6.5s | 359 KB | 270 KB
| **2.5.0** | **7.5s** | **5.2s** | **357 KB** | **259 KB**

**Allows USWDS notifications to render in all environments.** We removed the multiline strings that were causing our notification to cause build failures in environments like webpack. Now the Sass should compile properly in all environments. https://github.com/uswds/uswds/pull/3290

**Update to the most recent version of Public Sans.** Updated to Public Sans 1.008 for better readability and display. https://github.com/uswds/uswds/pull/3275

**Added missing `add-aspect()` mixin.** This adds the mixin equivalent to the `add-aspect` utility classes. https://github.com/uswds/uswds/pull/3283

**Improved error messaging for the `lh()` function.** Now it lets you know why it failed and how to fix the error. https://github.com/uswds/uswds/pull/3284

**Disabled JS in our Fractal library to remediate an out-of-date jQuery vulnerability.** https://github.com/uswds/uswds/pull/3274

Version 2.4.0

December 18, 2019

# What's new in USWDS 2.4.0

**Allow non-token values in theme color settings.** While USWDS promotes and encourages using our system tokens in theme color settings, agencies have a real need to occasionally use non-token colors. This includes instances where certain colors are mandated by law and cannot be easily changed. Now, teams can add non-token colors to theme color settings like `$theme-color-primary: #f00`. This new non-token value of `'primary'` will apply anywhere the `'primary'` token is used: functions, mixins, settings, and utilities. Using non-token values will throw a warning in the compile process, but this, like all compile warnings, can be disabled by setting `$theme-show-compile-warnings: false`. (https://github.com/uswds/uswds/pull/3258)

**Handle deprecations more gracefully.**  Occasionally the design system will deprecate variables or functionality. Now we'll display a deprecation message in the terminal when compiling USWDS Sass to better communicate these changes. (This notification can be disabled in settings.) We're also improving backward compatibility by supporting deprecated variables, functions, and mixins throughout the major version cycle. This way, we can continue to improve how our code is structured while minimizing the effects of this restructuring on your projects. (https://github.com/uswds/uswds/pull/3261)

This is how the deprecation warning prints in the terminal:

✉ USWDS Notifications
2.4.0: If your component settings aren't working as expected, make
sure you're importing the components settings in your Sass entry
point (often styles.scss) with `@import "uswds-theme-components"`.
A bug in 2.0 omitted that import.
2.2.0: We changed the names of some settings.
$theme-navigation-width → $theme-header-min-width
$theme-megamenu-logo-text-width → $theme-header-logo-text-width
2.0.2: We changed the names of some settings and mixins.
$theme-title-font-size → $theme-display-font-size
@include title → @include display
@include typeset-title → @include typeset-display
These are notifications from the USWDS team, not necessarily a
problem with your code.

Disable notifications using $theme-show-notifications: false

**Now components reliably respect their font settings.** Setting values like `$theme-footer-font-family` should set the font face for the entire component, but some CSS specificity quirks were overriding these values in some instances. Now, setting a component's font face works as expected, with no secret overrides.  (https://github.com/uswds/uswds/pull/3253)

### Bugfixes
- Added a `border-collapse: collapse` rule to our tables to to fix a bug introduced when we upgraded our version of Normalize. Thanks for the heads up @maya! (https://github.com/uswds/uswds/pull/3250)
- Removed a duplicate layout grid import (https://github.com/uswds/uswds/pull/3252)
- Fixed the focus outline's offset, which was being overridden by a specificity bug (https://github.com/uswds/uswds/pull/3259)

### Audit
**npm audit:** found 7 vulnerabilities (5 low, 2 high) in 30585 scanned packages
Both High vulnerabilities are related to Fractal and `lodash`

Version 1.6.13

November 26, 2019

## Starting point
`npm audit`: `965 vulnerabilities (96 low, 236 moderate, 623 high, 10 critical)`

## What we did
- Removed Fractal, since we are no longer making changes to component code
- Removed unused regression tests
- Added precompiled component previews and renders to a committed directory for testing
- Using `v1-master` and `v1-develop` as `v1` production branches

## Result
`npm audit`: `4 moderate severity vulnerabilities`

All current moderate vulnerabilities related to `jsdom > hoek`

Version 1.6.12

- Fix Snyk tests on Circle
- Fix cache bug on Circle

Version 1.6.11

November 25, 2019

- Changed Circle cache settings

Version 2.3.1

November 21, 2019

# What's new in USWDS 2.3.1

**Now the success icon looks like a checkmark and not a warning.** This fixes a bug introduced in `2.2.0` related to SVG normalization. (#3230) Thanks @nickscialli-usds


Version 2.3.0

November 20, 2019

# What's new in USWDS 2.3.0

**Properly include component theme variables:** Now we're properly including the component theme variables from `_uswds-theme-components.scss` in `theme/styles.scss` so anyone who uses that file in their Sass compile process (like users of `uswds-gulp`) will see component theme settings applied as expected. 

These should be the proper theme imports for USWDS projects:
@import 'uswds-theme-general';
@import 'uswds-theme-typography';
@import 'uswds-theme-components'; <-- previously missing
@import 'uswds-theme-spacing';
@import 'uswds-theme-color';
@import 'uswds-theme-utilities';
Issue: https://github.com/uswds/uswds/issues/3117

**Hero image theme setting default is now backward compatible:** The `$theme-hero-image` theme variable now has a default equivalent to its effective value pre `v2.2.0` so users that had a working version of their hero are more likely to see no issues upgrading to the latest version of USWDS. 
- Although the new default includes a variable reference to `$theme-image-path`, users can change this to any path needed. It need not refer to `$theme-image-path`. 
- This new default requires that the component theme variables (`uswds-theme-components`) be imported after `uswds-theme-general`. We suggest that `uswds-theme-components` be the last of the theme variables imported. 

Old default:
> `$theme-hero-image:  '..img/hero.png'`

### Markup changes
⚠️ We made a small change to the footer markup. This change fixes some small footer spacing issues — not adding this new markup will not negatively affect your existing footer, but adding it will make it better. See the diff: https://github.com/uswds/uswds/pull/3214/files

### Smaller issues
- **Megamenu sections now appear at the proper width in the mobile menu:** Fixes a megamenu column-width bug that made some subsection menu items appear at less than the full column width.
- **Contact Info underline scope applies to each item individually:** This fixes an issue where the `:hover` selector was too broad. This attaches it to the `a` link instead of the parent `div`.
- **Contact info spaced properly in slim footer:** Fixes a `grid-gap` error to assure that contact info items have space in-between.
- **Contact info displays properly regardless of whether utilities use important:** Fixes an issue where the contact info wouldn't display properly unless project utilities were set to use important. 
- **Open/close carets in the mobile big footer are now the proper size.**
- **Improved footer link spacing `@desktop` width.**
- **Updated and clarified all the font licenses.**
- **Added Public Sans v1.007**
- **Use [Prettier](https://prettier.io/) formatting for files.**
- **Completely install USWDS when building on Federalist.**
- **Update our security test with Snyk.**

Version 2.2.1

September 23, 2019

# What's new in USWDS 2.2.1

**Sass compiles properly:** Now importing `uswds` using `@import uswds` will compile properly. The `packages/uswds-components` package newly referenced by `uswds.scss` was using incorrect paths and now they point to the proper locations. 

> **Why did this happen?** A quirk of how Sass evaluates paths prevented us from seeing this error before we published the release. Sass will, apparently, accept paths relative both to the the file containing the `import` _and also_ to the entry point (ie, the primary file the compiler points to). The incorrect `/base` paths evaluated properly for us internally since `uswds.scss` is the entry point from which we compile our Sass (that is, we do not `@import uswds` from a separate file). By chance, `/base` is valid relative to this internal entry point. 
> **How are we preventing this in the future?** We've made the build process more strict in `uswds-site` (https://github.com/uswds/uswds-site/pull/816/commits/103dd3ff0569f3a6c61cfd254df031dfdb5c5045#diff-d0940386a71c685fc307161a767958b4R54) so it'll be far less likely that such a bug will make it through our testing. We may also change our internal build process to surface errors such as this one.

Version 2.2.0

September 19, 2019

# What's new in USWDS 2.2.0

**Extended megamenu now works:** This fixes a CSS specificity error introduced in 2.1.0 affecting the extended header's megamenu. (https://github.com/uswds/uswds/pull/3100)

**Primary nav indicators are properly aligned:** This fixes a spacing issue affecting the header nav indicator bars present since 2.0 that seems to have been a result of rounding errors in line-height calculation. (https://github.com/uswds/uswds/pull/3100)

**All component font functions now use role-based tokens:** Now code will generate properly, even if a user decides not to use a certain font type in their project (like `serif`). (https://github.com/uswds/uswds/pull/3103)
> Example: a project uses only a sans-serif font on their site, all other font types are set to `false`.

**Improved ARIA markup:** We no longer add manual ARIA roles to semantic elements with implicit roles (like `header`, `nav` and `footer`), as this is redundant in modern HTML 5. However, we now add unique and sensical identification to both our primary and secondary navigation with `aria-label`. (https://github.com/uswds/uswds/pull/3104)
> Reference: https://www.w3.org/WAI/tutorials/page-structure/regions/#navigation

**Consistent sizing for SVG assets:** Now our SVG image assets are sized and built consistently, so CSS styling affects each image as expected. Previously, inconsistent sizing and `viewBox` settings could cause unexpected effects or necessitate compensatory styling. (https://github.com/uswds/uswds/pull/3105)

Now, each SVG asset is set in a 64px max bounding box flush to the edge of the image — that is, the image is exactly 64px in the maximum dimension, with no space around the perimeter. This allows us to more accurately control the output with CSS. The image is minimally opinionated.

This PR affects:
- all SVG assets
- some components that use SVG assets
  - alerts
  - search
  - checkboxes
  - checklist

⚠️ **This change has the potential to affect any custom components built with existing SVG assets.**

- - -

**Header and banner width now controlled in settings:** Now there are explicit settings for controlling the max-width of the gov banner and the header. (https://github.com/uswds/uswds/pull/3106)

:warning: This change affects the markup of the megamenu.
:warning: This change affects settings. Replace instances of the deprecated setting with the new one. 

| old variable | 2.2.0+
| --- | ---
| `$theme-navigation-width` | `$theme-header-min-width`
| `$theme-megamenu-logo-text-width` | `$theme-header-logo-text-width` 

Your settings file will require the new settings below:

| file | setting variable | controls | default |
components | `$theme-banner-max-width` | maximum width of the banner | `desktop`
components | `$theme-header-max-width` | maximum width of the header | `desktop`
components | `$theme-header-min-width` | breakpoint at which full header shows | `desktop`
components | `$theme-header-logo-text-width` | width of the logo/title region of the header (replaces `$theme-megamenu-logo-text-width` | 33%
components | `$theme-megamenu-columns` | number of columns in the megamenu | 3

- - -

**Settings can control hero image:** Now you can change the hero image in settings! (https://github.com/uswds/uswds/pull/3107)

:warning: This change affects settings. Your settings file will require the new settings below:

| file | setting variable | controls | default |
components | `$theme-hero image` | path to the hero image, relative to the compiled stylesheet | `'../img/hero.png'`

- - -

**Improve package documentation and usage:** This improves the package documentation in the theme `styles.scss` by including all available packages in the comments. It also modifies the package contents of `uswds-components` to require the `required` and `global` packages — to be consistent with other packages. (https://github.com/uswds/uswds/pull/3108)

:warning: If you use the `uswds-components` package, you will no need to include the `required` and `global` packages before including `uswds-components`. 


Version 2.1.0

August 14, 2019

Made it simpler to subset the design system and include only the components your project needs with **USWDS packages**.
- Thanks @turnerhayes for getting the ball rolling here, even if the final product might not be what you envisioned!
- Created custom packages in `stylesheets/packages` used to import only code related to the component package (ie `@import uswds-banner`)
- Analyzed each USWDS component's stylesheet dependencies
- Left existing default build process alone (ie @import uswds)
- Allows users to dramatically reduce the USWDS code footprint

| package | .css | .min | .zip
| --- | --- | --- | ---
**default USWDS** | **359** | **271** | **40 KB**
form-controls | 18 | 15 |  3
form-templates | 60 | 47 | 6
typography | 17 | 15 | 3
validation | 32 | 28 | 5

usa-tag | 10 | 9 | 2
usa-header + usa-footer | 162 | 72 | 10
usa-banner + usa-footer | 99 | 55 | 7

Reorganized the source code (in the `stylesheets` directory) to better reflect its relationship to the build process:
- Split subcomponents into separate files
- Move global stylesheets into their own folder
- Move all code-emitting source out of `required` dependencies
