If the specified `index` is equal to the length of the rules rule collection, the rule will be added to the end of the rule. If index is not given or None rule will be appended to rule list. :returns: the index of the newly inserted rule. :exceptions: - :exc:`~xml.dom.HierarchyRequestErr`: Raised if the `rule` cannot be inserted at the specified `index`, e.g., if an @import rule is inserted after a standard rule set or other at-rule. - :exc:`~xml.dom.IndexSizeErr`: Raised if the specified `index` is not a valid insertion point. - :exc:`~xml.dom.NoModificationAllowedErr`: Raised if this rule is readonly. - :exc:`~xml.dom.SyntaxErr`: Raised if the specified `rule` has a syntax error and is unparsable. )rdrfr#r#r$rPs $zCSSRuleRules.insertRule)NNr1)r@rArBrCrrOrVrDrLrSrdrgrhrPrGr#r#r!r$rHs  ,'rH) rC__all__xml.domr+ cssutils.utilrIutilBase2rrHr#r#r#r$s
