{{APIRef("CSSOM")}}{{deprecated_header}}

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

[!NOTE] As a legacy property, you should not use rules and should instead use the preferred {{domxref("CSSStyleSheet.cssRules", "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.

Value

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