Creating Background for Sidebar

[kristabelle89]

I'm trying to figure out how one would go about making the background of the Sidebar Redux Plugin of a photo instead of the color of the body of the forum.  I hope this is in the right place!

I can adjust codings but I don't know how to create my own codes, just fyi.

Usually you would use the CSS Property, background-image.

It's set up like this:

background-image: url('http://image.png');

I'm really sorry but I still can't find that >.<

EDIT: Nevermind I'm an idiot I found it staring at me.  Thanks!
