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

{% comment %} Necessary for following accessibility best practices. {% endcomment %}

{% highlight html %} Skip to main content {% endhighlight %}

{% highlight scss %} // Usage as a mixin .skip-navigation { @include sr-only; @include sr-only-focusable; } {% endhighlight %}
