API#

useFocusRing( (props: AriaFocusRingProps )): FocusRingAria

Introduction#

The useFocusRing hook returns whether a focus ring should be displayed to indicate keyboard focus for a component. 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.

If CSS classes are being used for styling, see the FocusRing component for a shortcut.

Options#

NameTypeDefaultDescription
withinboolean'false'

Whether to show the focus ring when something inside the container element has focus (true), or only if the container itself has focus (false).

isTextInputboolean—Whether the element is a text input.
autoFocusboolean—Whether the element will be auto focused.

Result#

isFocusVisiblebooleanWhether keyboard focus should be visible.
focusPropsDOMAttributesProps to apply to the container element with the focus ring.

Example#

This example shows how to use useFocusRing to adjust styling when keyboard focus is on a button. Specifically, the outline property is used to create the focus ring when isFocusVisible is true.

See useCheckbox, useRadioGroup, and useSwitch for more advanced examples of focus rings with other styling techniques.
