Focus

This package contains focus-related utilities.

Focus rings

To add a focus ring to an element, ensure the following requirements:

• The focus ring should be a child of the element which it is offset from.
• The element which the focus ring is offset from should have a non-static position CSS value. This is because the focus ring has position: absolute and is then positioned relative to its container element.
• The focus ring can be shown in Sass via focus-ring-theme.show-focus-ring().

See the following example:

<button class="mdc-button">
	<span>Click me!</span>
	<div class="mdc-focus-ring"></div>
</button>

.mdc-button {
  position: relative;
}

.mdc-focus-ring {
  @include focus-ring-theme.static-styles();
  @include focus-ring-theme.theme-styles(focus-ring-theme.$light-theme);
}

.mdc-button:focus-visible .mdc-focus-ring {
  @include focus-ring-theme.show-focus-ring();
}
