This a question about the Thematic CSS.
I know that style.css imports the other CSS from library/styles. So if I want to change to a 3c-fixed grid I simply replace the default (2c-r-fixed.css) style, where it says "Apply a basic layout"
However I'd quite like to swap between 2 and 3 columns layouts in some of my pages. On sites I've built before I used a copy of the index for any new templates, inserted a new template name and made any relevant CSS changes. But there was only one CSS file, so it was simple enough.
So my question is: Is there a simple way to use more than one layout style?
Thanks for your help
