CSSStyleSheet: rules property
Deprecated
Avoid using this feature in new projects. This feature may be a candidate for removal from web standards or browsers.
The rules read-only property of the CSSStyleSheet interface is a deprecated legacy property. 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 should 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.
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.
