CSSGroupingRule

The CSSGroupingRule interface of the CSS Object Model represents any CSS at-rule that contains other rules nested within it.

Objects deriving from it:

• CSSConditionRule and its children: CSSMediaRule and CSSSupportsRule.
• CSSPageRule

The syntax is described using the WebIDL format.

interface CSSGroupingRule : CSSRule {
    readonly attribute CSSRuleList cssRules;
    unsigned long insertRule (DOMString rule, unsigned long index);
    void deleteRule (unsigned long index);
}

The CSSGroupingRule derives from CSSRule and inherits all properties of this class. It has one specific property:

CSSGroupingRule.cssRules Read only

Inherits methods from its ancestor CSSRule.

CSSGroupingRule.deleteRule
