You can do this using the standard CSS attribute selectors. See http://www.w3.org/TR/REC-CSS2/selector.html#attribute-selectors myelement:before { display: ZZZ; content: "my label 1 " mycontrol(); } myelement[myoptionalattr]:before { display: ZZZ; content: "my label 1 " mycontrol() " my label 2 " myothercontrol(); }
