Most of the formatting is hard-coded in the sidebox file, using antiquated and possibly deprecated tag attributes. The best solution would be to rewrite that part of the file to add classes and remove hard-coded styling, so the styling can be handled in the stylesheet. That's really something TM should be doing, but they don't care about standards or best practice or customizability, only what will get their look in every browser no matter how old.
