There are 8 different basic usable website themes I can think of. I've listed them below. My intention is to find minimal mark-up that will produce these themes, with as wide a range of browsers as possible support.

One column	Three fixed columns
Three column fluid center	Three columns - fluid left
Three columns fluid right	Two fixed columns
Two columns - fluid left	Two columns - fluid right

Does anyone have any suggestions of an Open Source solution to these themes? I'm sure they have all been created before. Why re-invent the wheel?
