Well, there are really only 2 ways to do it; unless you want to go overboard and use JS.

Apparently I wasn't paying enough attention. My statement that the import on Common.css is what you want was not correct. That is actually importing a subpage. To get an import statement that works, it is almost exactly like that except you need to remove "/hilite". Also, if you are going to keep using the hilite CSS, consider moving it to an actual CSS page.
