There may well be a way to do a CSS Insert and accomplish the same thing but I haven't figured that tool out yet (what it does and doesn't does). Anyway, here's the code for 3.3.3's Style.css file -- my simple changes in red:
Code:
/* "current" page and hover */ ul.rMenu li.current_page_item a:link, ul.rMenu li.current_page_item a:active, ul.rMenu li.current_page_item a:hover, ul.rMenu li.current_page_item a:visited, ul.rMenu li a:hover { font-weight: bold; text-decoration: underline; } /*added*/ /* "current" category and hover */ ul#rmenu li.current-cat a:link, ul#rmenu li.current-cat a:active, ul#rmenu li.current-cat a:hover, ul#rmenu li.current-cat a:visited, ul#rmenu li a:hover { font-weight: bold; text-decoration: underline; }
P.S.S. Make a backup copy of this file before making the changes.
Hope this helps.
