Thank you very much for all the time to help me out. I will try what you suggest. You have made it as clear as can be even for someone like me who's a bit dense about CSS but wants to experiment with it anyway.
Oh too bad about Chrome. But that will have to wait until I have time to do some more research for me to try and suss it out. (and until I get the opportunity to download it) It took me long enough to get the code to work in both IE and Firefox and I'm good at pretending I know what I'm doing in those browsers, haha.
