First of all I hope I am posting in the right area, please redirect me if not.
I'm fairly new to writing websites and I'm having some cross-browser issues: my listings website www.swingoutlondon.co.uk renders correctly in Firefox Chrome and Safari, but not on IE7 for Windows XP - The two floated columns don't sit next to each other, and the elements in the left-hand column ('Learn!') don't sit within their enclosing <li> elements.
The XHTML and CSS validated last time I checked, so I suspect this may be a bug in IE which I need to account for, but I can't fathom what's going wrong.
Any thoughts to get me started (and critique/abuse about the site itself) would be greatfully received.
