Standards information

There are no standards that apply here.

Remarks

You can use this object to retrieve style sheet information, such as the URL of the source file for the style sheet and the element in the document that owns (defines) the style sheet. You can also use it to modify style sheets.

You can retrieve a styleSheet object from the styleSheets collection or from the imports collection. Each item in these collections is a style sheet. A styleSheet object is available for a style sheet only if it is included in a document with a style or link element, or with an @import statement in a style element.

Note For the style element, styleSheet is no longer supported. Starting with Internet Explorer 11, use sheet.

Examples

This example uses the styleSheet object to change the cascading style sheets (CSS) values of inline and imported styles.
