:has()
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)');
Syntax
:has( <relative-selector-list> )where
<relative-selector-list> = <relative-selector>#where
<relative-selector> = <combinator>? <complex-selector>where
<combinator> = '>' | '+' | '~' | [ '||' ]
<complex-selector> = <compound-selector> [ <combinator>? <compound-selector> ]*where
<compound-selector> = [ <type-selector>? <subclass-selector>* [ <pseudo-element-selector> <pseudo-class-selector>* ]* ]!where
<type-selector> = <wq-name> | <ns-prefix>? '*'
<subclass-selector> = <id-selector> | <class-selector> | <attribute-selector> | <pseudo-class-selector>
<pseudo-element-selector> = ':' <pseudo-class-selector>
<pseudo-class-selector> = ':' <ident-token> | ':' <function-token> <any-value> ')'where
<wq-name> = <ns-prefix>? <ident-token>
<ns-prefix> = [ <ident-token> | '*' ]? |
<id-selector> = <hash-token>
<class-selector> = '.' <ident-token>
<attribute-selector> = '[' <wq-name> ']' | '[' <wq-name> <attr-matcher> [ <string-token> | <ident-token> ] <attr-modifier>? ']'where
<attr-matcher> = [ '~' | | | '^' | '$' | '*' ]? '='
<attr-modifier> = i | s
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)
