The :has() CSS pseudo-class represents an element if any of the selectors passed as parameters (relative to the :scope of the given element) match at least one element.

/* Selects any <a>, as long as it has an <img> element directly inside it  */ /* Note that this is not supported in any browser yet */ let test = document.querySelector('a:has(> img)');

Description

The :has() pseudo-class takes a relative selector list as an argument. In earlier revisions of the CSS Selectors Level 4 specification, :has had a limitation that it couldn't be used within stylesheets. Instead, it could only be used with functions like document.querySelector(); this was due to performance concerns. This limitation has been removed because no browser implemented it that way. Instead, browsers currently only support the use of :has() within stylesheets.

Examples

Matching <a> elements that directly contain an <img>

The following selector matches only <a> elements that directly contain an <img> child:

a:has(> img) 

Matching <h1> elements that are followed by a <p>

The following selector matches <h1> elements only if they have a <p> element directly following them:

h1:has(+ p)
