I am using the 2 column, liquid, sidebar w/header/footer template in Dreamweaver CS5. I have two questions but I will only ask one at a time

How do I fill in that bottom left block with a color? I have changed the whole background to what I want but one section of the sidebar(bottom left)will not change Can someone tell me if I should just put a screenshot here or should I copy and paste code?

ty much, Denise
