My site looks rubbish in Firefox
I don't regard myself as a web-design expert by any means. I just do my best as a self-taught Dreamweaver user. However, I thought I'd got the school website looking reasonably OK, until I switched to Firefox. Now I find gaps opening up between the rows of the main menu which looks a bit rubbish. Eg, note the gap between "Welcome" and "Headteacher" on the front page, and the way the menu skips about, eg by clicking between "Business" and "PE" on the "Subjects" page. This all looks fine in IE7.
I know it's difficult to say without seeing how I've set it up, but I was just wondering if anyone could guess what the problem might be...? Some incompatibility between IE and Firefox on the tables front, or issues with Firefox and Dreamweaver 8. (All the layout is done with tables and a few shims because I don't know better, but I'm not about to attempt a complete redesign.)
Any suggestions appreciated...
