How we built it

CSSConditionRule interface

The CSSConditionRule interface inherits from CSSGroupingRule. CSSMediaRule and CSSSupportsRule both inherit from CSSConditionRule. Before the introduction of CSSConditionRule in Blink, CSSMediaRule inherited from CSSGroupingRule, while CSSSupportsRule inherited from CSSRule and duplicated the members of CSSGroupingRule.
