public abstract CSSRuleList getCssRules ()

The list of all CSS rules contained within the style sheet. This includes both rule sets and at-rules.

public abstract CSSRule getOwnerRule ()

rule The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content.
index The index within the style sheet's rule list of the rule before which to insert the specified rule. If the specified index is equal to the length of the style sheet's rule collection, the rule will be added to the end of the style sheet.
