Hide an element to all devices except screen readers with .sr-only. Use .sr-only-focusable to show the element only when it's focused (e.g. by a keyboard-only user). Can also be used as mixins.

{{< example >}}

Title for screen readers

Skip to main content {{< /example >}}

{{< highlight scss >}} // Usage as a mixin

.sr-only-title { @include sr-only; }

.skip-navigation { @include sr-only-focusable; } {{< /highlight >}}
