rulesNN n/a   IE 4   DOM n/a

A collection of all rules defined or imported for a styleSheet object. Collection members are sorted in source code order. Internet Explorer lets you use array notation or parentheses to access a single row in the collection (e.g., document.all.myTable.rows[0], document.all.myTable.rows(0)). Unlike some other collections that have methods for adding or removing items, a styleSheet object's rule is added via methods of the styleSheet object.
