I am using Twenty Eleven 1.3 theme and my page looks something like this:
On the top there is the "NAME" of my page on a white background
Under the "NAME" there is a "HEADER IMAGE"
Under the "HEADER IMAGE" I have two things:
On my left side there is "PAGE CONTENT" on a white background
On the right side I have a "SIDE BAR" with my links on a white
Now what I am trying to do is to set a different background color to my "NAME", "PAGE CONTENT" and "SIDE BAR".
The problem is I don't know where to do this.
