I haven't tested it but I have a probing question question...

I would create a 3 column layout and maybe I use css3 layout module (and jQuery + css-template-layout for IE)but is it possible to remove/ hide a column with this module (css3 module and also your plugin)?

In a example there are 3 columns. Left and right column html source code will removed if empty (php if in template). Do that work with css3 layout too (without changing css code)? And will it work with css-template-layout?

Best regards
