:focus-within

The :focus-within CSS pseudo-class matches an element if the element or any of its descendants are focused. In other words, it represents an element that is itself matched by the :focus pseudo-class or has a descendant that is matched by :focus. (This includes descendants in shadow trees.)

Try it

This selector is useful, to take a common example, for highlighting an entire <form> container when the user focuses on one of its <input> fields.

Syntax

:focus-within {
  /* ... */
}

Examples

In this example, the form will receive special coloring styles when either text input receives focus.

HTML

<p>Try typing into this form.</p>

<form>
  <label for="given_name">Given Name:</label>
  <input id="given_name" type="text" />
  <br />
  <label for="family_name">Family Name:</label>
  <input id="family_name" type="text" />
</form>
