BrightBox is an awesome theme and I'm so excited about how the functionality is going to improve the site I'm building by leaps and bounds. I'm encountering a bit of an issue though. Looking through my CSS editor, I cant find any mention of a background image that creates the deep blue behind the header and footer. It occurred to me that you can do gradients with HTML 5 and CSS3, but even that is driven with CSS and theres no mention of anything like that going on, so I am a little bit confused as to how to begin customizing this theme and really molding it into the colors and design I need. Any advice?
