-If the document language specifies how the (human) content language of an element is determined, it is possible to write selectors that represent an element based on its content language. The :lang() pseudo-class, which accepts a comma-separated list of one or more language ranges, represents an element whose content language is one of the languages listed in its argument. Each language range in :lang() must be a valid CSS &lt;ident&gt; or &lt;string&gt;. (Thus language ranges containing asterisks, for example, must be either correctly escaped or quoted as strings, e.g. :lang(\*-Latn) or :lang("*-Latn").)

The :lang() pseudo-class, which accepts a comma-separated list of one or more language ranges, represents an element whose content language is one of the languages listed in its argument.
