cssRules, CSSRuleList, rules

NN 6 IE 4 DOM 2

A collection of cssRule (Netscape 6 and IE 5/Mac) or rule (IE 4 and later) objects that are members of a styleSheet object. The W3C DOM abstract representation of this collection is called a CSSRuleList object. Members of this collection are accessed only via their integer index number, but you may iterate through the collection and examine properties of each rule object (such as the selectorText property) to distinguish one rule from another.
