changing rollovers

Try using Firefox with the Firebug add-on for this kind of CSS work.

i did & i can’t figure it out because I don’t know how to apply a separate css rule for rollovers within a page without affecting the rollover of all the menu titles on that page.

I’m sorry but it is beyond the scope of these forums to teach basic CSS but you can find some useful CSS resources at:
