Hi,
I'm sure this may sound like a very simple question to many ..

How do you change the background color of your template / storefront?
I'm using the free template 2.

I've tried editing the stylesheet CSS, to make it black using background-color:#000000;  .. but this does not seem to work. Would anyone be able to tell me the exact file location I should go to and the edits that need to be made?

Thanks
