I have found a page which does what I am looking for:

http://jsfiddle.net/9Z363/93

This seems a bit over complicated for doing such. There is surely something simpler.

Basically:

1. Left column is fixed
2. Right column takes a much as possible
3. Right column wraps as needed

However, I would like the right column to always show a minimum of 260 pixels. So, when it cannot show 260 pixels, it will then wrap under the first column.
