RE: Sidebar style

Hi there,

I'm very new to the Atahualpa theme and Wordpress - having only created static html sites before.

How can I change the style of the menus (?) on the right? I want something like this if possible. I like how each section is boxed off and the black color behind the "categories" and "popular post" sections.

Is this possible to do for a novice?


Cheers,
Michelle
