@CentauriSep 09.2008 — #First off, your IE only css file should contain [B]ONLY[/B] any styles you want changed from the main css, and should not repeat the main css - ie. it should be blank for starters until you need something [B]different[/B] for IE. You usually only need a separate sheet for IE6 anyway - IE7 is much better behaved.
The navigation problems are due to the way different browsers indent lists - FF uses left padding but IE uses left margin, and it is this margin causing the issues here - general rule is to control BOTH margins and padding to display lists the same cross-browser.
The other problems have something to do with the tables, but I don't know what that might be as I only use tables for their proper purpose, and [B]never[/B] for layout......
Also note that IE6 does not support :hover on anything other than <a> links, so your hover does not work - better off setting the navigation <a>s as block display, sizing them and applying the backgrounds and hover to them instead of the <li>s.
