How do I split a WordPress theme into 2 columns?

I want to split my WordPress theme (I'm working from The Buffet Framework) into 2 columns, like a magazine or newspaper. The term "2-column" usually refers to a sidebar, but I want to get 2 columns of posts in addition to the right sidebar. I'm assuming this is just a simple matter of some basic HTML or CSS column creating, but I'm not sure how to go about it. Thanks in advance 开发者_StackOverflowfor your help.

I think you're talking about multi-column layout in CSS3 which is not widely supported yet:

If you want wider support, try jQuery to do this:

note: it crashes occassionally (especially with images)
