I wish to split my WordPress theme (I am working from The Buffet Framework) into 2 posts, just like a magazine or newspaper. The word "2-column" usually describes a sidebar, but I wish to get 2 posts of posts additionally right sidebar. I am presuming case rather simple of some fundamental HTML or CSS column creating, but I am unsure how to pull off it. Thanks ahead of time for the help.

If you would like wider support, try jQuery to get this done:
note: it crashes occassionally (particularly with images)
