Thanks, I removed float left with firebug and it solved the problem completely.
The trouble is I don’t seem to have a compressed.ccs file anywhere, despite firebox showing one. It isn’t showing in my theme editor from the admin dashboard, or via my ftp for the site. The only css files I can see are style.css and ie.css, and this bit of code doesn’t appear in either. Any ideas why compressed.css isn’t showing? Or how I could access it?
Thanks
