public interface CSSRule
CSSRule
interface is the abstract base interface for any
type of CSS statement. This includes both rule sets and at-rules. An
implementation is expected to preserve all rules specified in a CSS style
sheet, even if the rule is not recognized by the parser. Unrecognized
rules are represented using the CSSUnknownRule
interface.
