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

More Details for :focus-visible

:focus-visible

The :focus-visible pseudo-class applies while an element matches the :focus pseudo-class and the UA (User Agent) 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).

Syntax

:focus-visible

Examples

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: 2px solid red;   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

Low vision

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.

Cognition

It may not be obvious as to why the focus indicator is appearing and disappearing if a person is using mixed forms of input. For users with cognitive concerns, or who are less technologically literate, this lack of consistent behavior for interactive elements may be confusing.
