Visually hide an element while still allowing it to be exposed to assistive technologies (such as screen readers) with `.visually-hidden`. Use `.visually-hidden-focusable` to visually hide an element by default, but to display it when it's focused (e.g. by a keyboard-only user). Can also be used as mixins.
Visually hide an element while still allowing it to be exposed to assistive technologies (such as screen readers) with `.visually-hidden`. Use `.visually-hidden-focusable` to visually hide an element by default, but to display it when it's focused (e.g. by a keyboard-only user). `.visually-hidden-focusable` can also be applied to a container–thanks to `:focus-within`, the container will be displayed when any child element of the container receives focus.
{{< example >}}
<h2 class="visually-hidden">Title for screen readers</h2>
<a class="visually-hidden-focusable" href="#content">Skip to main content</a>
<div class="visually-hidden-focusable">A container with a <a href="#">focusable element</a>.</div>
{{< /example >}}
Both `visually-hidden` and `visually-hidden-focusable` can also be used as mixins.
```scss
// Usage as a mixin

### JavaScript
