ICSSStyleSheet

ICSSStyleSheet interface

The CSSStyleSheet interface represents a single CSS stylesheet, and lets you inspect and modify the list of rules contained in the stylesheet. It inherits properties and methods from its parent, StyleSheet.

A stylesheet consists of a collection of CSSRule objects representing each of the rules in the stylesheet. The rules are contained in a CSSRuleList, which can be obtained from the stylesheet’s cssRules property.

For example, one rule might be a CSSStyleRule object containing a style such as

h1, h2 {   font-size: 16pt; }

Another rule might be an at-rule such as @import or @media, and so forth.
