Thank you, Frank.
I managed to find this
layout through one of the links at the URL you provided.
How does it look in comparison to the one that Matthew James Taylor provides? Any pros/cons? It definitely seems much easier to edit, but I don't want to use it if it means sacrificing older browser compatibility.
If anyone else has some input and/or good fixed-width 2-1-3 layout options, please let me know.
