The :lang selector targets any element that contains the lang attribute and the relevant language subtag value.
All web documents should be defined with a language to assist devices, search engines and assistive technologies.
The primary language for each web document can be defined using the lang attribute inside the <html> element.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Title</title>
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
The lang attribute can be added to HTML elements to define languages for sections of a web document.
<!-- Italian -->
<div lang="it">
Mi sei mancato molto
</div>!
<!-- Latvian -->
<span lang="lv">
Labvakar
</span>
The values inside the lang attribute are called Language subtags.
These language subtags are defined in the IANA Language Subtag Registry.
The :lang(c) pseudo-class selector is written using an optional element, followed by a ":", followed by "lang", followed by "(c)".
The "(c)" is a language subtag placed inside brackets.
/* syntax */
:lang(c) { }
E:lang(c) { }
/* French example */
p:lang(fr) { }
/* Punjabi example */
span:lang(pa) { }
Whitespace is not permitted within the selector.
/* Valid */
:lang(bs) { }
/* Invalid */
: lang (bs) { }
This selector targets any element that contains the lang attribute and the relevant language subtag value.
In the following example, only the <p> element with lang value of fr will be selected.
/* CSS selector */
p:lang(fr) { }
<!-- HTML markup -->
<p lang="fr">Adieu</p>
<p lang="jw">Sugeng rawuh</p>
