rule object

[This documentation is preliminary and is subject to change.]

Represents a style within a style sheet that consists of a selector and one or more declarations.

Standards information

There are no standards that apply here.

Remarks

The rule object defines a set of Cascading Style Sheets (CSS) attributes applied to a set of HTML elements. For example, a rule consisting of the selector H1 and the declaration font-family:Arial defines all H1 elements to render in the Arial font.

Examples

This example uses a rule object consisting of the selector H1 to define a single rule that changes the H1 headings in a document to red.

<STYLE>
    H1 { color: red }
</STYLE>

If the style sheet containing the preceding rule is the first style sheet in the document, the following code returns the rule object associated with the rule.

oRule=document.styleSheets(0).rules(0)
