The :focus-visible pseudo-class applies while an element matches the :focus pseudo-class and the UA determines via heuristics that the focus should be made evident on the element. (Many browsers show a “focus ring” by default in this case.)

This selector is useful to provide a different focus indicator based on the user’s input modality (mouse vs. keyboard).

Note that Firefox supports similar functionality through an older, prefixed pseudo-class — :-moz-focusring. See the :-moz-focusring page for more details.

Syntax

:focus-visible

Example

Basic example

In this example, the :focus-visible selector uses the UA's behavior to determine when to match. Compare what happens when you click on the different controls with a mouse, versus when you tab through them using a keyboard. Note the difference in behavior from elements styled with :focus.

<input value="Default styles"><br>
<button>Default styles</button><br>
<input class="focus-only" value=":focus only"><br>
<button class="focus-only">:focus only</button><br>
<input class="focus-visible-only" value=":focus-visible only"><br>
<button class="focus-visible-only">:focus-visible only</button>
input, button {
  margin: 10px;
}

.focus-only:focus {
  outline: 2px solid black;  
}

.focus-visible-only:focus-visible {
  outline: 4px dashed darkorange;
}

Selectively showing the focus indicator

A custom control, such as a custom element button, can use :focus-visible to selectively apply a focus indicator only on keyboard-focus. This matches the native focus behavior for controls like <button>.

<custom-button tabindex="0" role="button">Click Me</custom-button>
custom-button {
  display: inline-block;
  margin: 10px;
}

custom-button:focus {
  /* Provide a fallback style for browsers
     that don't support :focus-visible */
  outline: none;
  background: lightgrey;
}

custom-button:focus:not(:focus-visible) {
  /* Remove the focus indicator on mouse-focus for browsers
     that do support :focus-visible */
  background: transparent;
}

custom-button:focus-visible {
  /* Draw a very noticeable focus style for
     keyboard-focus on browsers that do support
     :focus-visible */
  outline: 4px dashed darkorange;
  background: transparent;
}

Polyfill

You can polyfill :focus-visible using focus-visible.js.

Accessibility Concerns

Make sure the visual focus indicator can be seen by people with low vision.  This will also benefit anyone use a screen in a brightly lit space (like outside in the sun).   WCAG 2.1 SC 1.4.11 Non-Text Contrast requires that the visual focus indicator be at least 3 to 1.
