I’m attempting to showcase 3 different service models, similar to what you see on http://www.leadpages.net/ however without being able to change the background color of a column, it’s hard to do. An easy way to do this would be to change the background of a sidebar, and use the sidebar widget in the page builder to represent each model. Is it possible to change the background color of a sidebar, or is there a better way to do this that I’m not thinking of?
