I won't admit how much time I have already spent on this... Any input would be hugely appreciated.
One of our clients needs a customized layout that is usually pretty simple, but I keep hitting roadblocks. Ex. The category page will use the left sidebar layout. The designs require:

. There is a blue band that spans the page width that needs to be placed at the top of the page, but after the header. I tried many different approaches to test adding this element to the LeftSidebar.master under the main folder and under the fixed folder. Nothing breaks, nothing publishes.
Any ideas on how I might be able to approach this?
Thanks!
