Whitespace [~=] attribute selector

Exactly matches the specified attribute value in a space-delimited list of values.

CSS 2.1, Section 5.8.1

 

Syntax

[att~=val] {...}

Parameters

att

Must be either an Identifier or a String.

val

Must be either an Identifier or a String.

Standards information

Remarks

Note  Requires Windows Internet Explorer 7 or later.

Note  Attribute selectors are not supported in webpages that are displayed in the Microsoft Internet Explorer 5 document mode (also known as "Quirks" mode). To use attribute selectors, add a !DOCTYPE directive that specifies a standards-based document. For more information, see Defining Document Compatibility.

Attributes are case-sensitive.

If the target val contains whitespace, the rule will not match anything.

Examples

The following style rule selects any element with an "attr" attribute whose value contains a whitespace-delimited list of words, one of which is the token "Two".


<!DOCTYPE html>
<html>
  <head>
    <style type="text/css">
      .test         { display:none; }
      [attr~="Two"] { display:block; }
    </style>
  </head>
  <body>
    <div class="test" attr="One Two Three">Test for [~=] (Whitespace) succeeded.</div>
  </body>
</html>
