Obsolete
This feature is obsolete.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.
