Is it possible to create variable width columns for equal height? For example, lets say I have a 2 column layout and in column 1 there are 2 rows that contain an image in each row. then in column 2 there is a single vertical image.

Without having to size the images, I want the images/columns to be 100% width of the viewport and maintain height as well. Right now I have a gap.

Here is an example: http://cl.ly/image/3l0L1a1p1Y2E

The white space illustrated is the gap that I\'m experiencing unfortunately.
