Web/API/CSSStyleSheet/rules

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

rules is a deprecated legacy property of the CSSStyleSheet interface. Functionally identical to the preferred cssRules property, it provides access to a live-updating list of the CSS rules comprising the stylesheet.

Note: As a legacy property, you not use rules and should instead use the preferred cssRules. While rules is unlikely to be removed soon, its availability is not as widespread and using it will result in compatibility problems for your site or app.

Syntax

var rules = cssStyleSheet.rules;

Value

A live-updating CSSRuleList containing each of the CSS rules making up the stylesheet. Each entry in the rule list is a CSSRule object describing one rule making up the stylesheet.
