Introduction#

FocusRing is a utility component that can be used to apply a CSS class when an element has keyboard focus. This helps keyboard users determine which element on a page or in an application has keyboard focus as they navigate around. Focus rings are only visible when interacting with a keyboard so as not to distract mouse and touch screen users. When we are unable to detect if the user is using a mouse or touch screen, such as switching in from a different tab, we show the focus ring.

If CSS classes are not being used for styling, see useFocusRing for a hooks version.
