Favourite methods for 3 coloured column, flexible CSS layouts
Three column CSS layouts can be tricky. One of my favourite approaches to resolving full height, coloured sidebars is faux columns. But what if you need fixed width sidebars with a flexible content area? There are a few approaches available (have a look at this list of three column layouts) but my favourite method uses no positioning and no hacks. Check it out here, courtesy of Petr Staníček.
The only issue I can see is that your content div code is located beneath the sidebar code. If search optimization is a priority, this might have a small effect on keyword prominence.
