Inserts a new rule into the media block.
retVal = object.insertRule(bstrRule, lIndex);
- bstrRule [in]
The parsable text that represents 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.
- lIndex [in]
The index within the media block's rule collection. The rule is inserted immediately before this index. If the specified index is equal to the length of the media block's rule collection, the rule is added to the end of the media block.
