Visually Hidden
Provides anounced text for screen readers that is not visible in other screens.
<VisuallyHidden> is the logical opposite of the aria-hidden attribute.
In the following example, screen readers will announce "Save" and will ignore the icon; the browser displays the icon and ignores the text.
import { VisuallyHidden, Icon } from 'matterial'
<button>
  <VisuallyHidden>Save</VisuallyHidden>
  <Icon icon="Download" aria-hidden />
</button>
