Hyphen attribute selector

Matches any property value that is defined with a hyphen-separated list of words when the first word is exactly equal to the value specified in the rule. This selector is generally only used to apply rules for language variants.

Syntax

[attr|=val] {sRules }

Possible values

Remarks

Property selectors are enabled only in standards-compliant mode (strict !DOCTYPE).

The hyphen is used primarily as a delimiter for language codes.

Attributes are case-sensitive.

Example

The following style rule selects any property whose value begins with "en" and is immediately followed by a hyphen:

<style>
    .test        {display: none;}
    [attr|="en"] {display: block;}
</style>

<div class="test" attr="en-us">Test for [|=] (Hyphen) succeeded.</div>

Standards information

This selector is defined in Cascading Style Sheets (CSS), Level 2, Revision 1 (CSS2.1) .
