so, building some html construct, i tried to add to templatestyles something line this:
.skin-minerva .myclass_X { display: none; }
however, this does not work, since the extension adds another class .mw-parser-output, and since the skin class belongs to the body, no element matches
.mw-parser-output .skin-minerva .myclass_X { display: none; }
i think the extension should treat classes that looks like skin-XXXX nicer, and parse
.skin-minerva .mw-parser-output .myclass_X { display: none; }
instead, so i can choose to be "skin sensitive".
peace.
