I am currently running the Sapphire template. I’ve noticed that I’m unable to use the dark blue background surrounding the blog template. I am new to CSS and can’t understand it for the life of me. Am I able to apply images (banners, etc) to the dark blue background or will I need to find another template to do this. None of the templates that I like are big enough to fit banner adds in the sidebars. I’d like to be able to use the full page if possible.
