Also if anyone could help me make the divs expandable but still aligned that would be great.

[Mr-Trainor]

I've never coded multi-collum layouts so I'm not expert but the main content and latest content are both on floateft, shouldnt one of them be on the right?

[redtom]

IE Handles the sizes of things wrong, where as Firefox displays them right. make your collums slightly smaller and it should appear fine, I havent read over your code so I could be wrong.

[MattFr]

The best bet for 2 column layouts is to set a fixed container width then use fluid percentages within. That's my preference anyway.

[Firehorse]

Fixed the issue with some help from Recursion. Needed to have separate css rules for IE and firefox, bit annoying really.

+Rep to all who posted. MattFr I need to spread.
