I want to use the Blueprint CSS framework for this site I’m working on: http://jsfiddle.net/timkl/uaSe3/
It allows me to layout my website in a nice 24 column grid.
However I want the background on my sitemap-div to stretch 100% horisontally in the browser, like this:

How would you go about this? Would the best solution be to put the sitemap-div outside the Blueprint container, or is there some kind of ninja CSS-trick that would allow me to do this without altering my markup?
Hope the above makes sense, any hints is highly appreciated 🙂

You’ll need to remove it from the parent container. There’s no way using CSS to make that container behave as you need it to if you don’t..
