My b2evolution Version: Not Entered

Hi there,

I attempted to change the white portion of the Intense skin layout (the part I would consider the background of the content area), but found myself pretty confused after perusing through the CSS code.

Does anyone know what file I should be in and what to look for?

I don't want to change the actual background color because that actually doesn't do anything. There is already a background image of some kind for the grey area that is behind the white area.

If anyone can point me in the right direction, that would be awesome.

Thank you,
Amy
