Decreasing space between sideboxes?

[shaerah]

After spending the morning looking, I found where to make the sidebox container background color. #navColumnOne, #navColumnTwo.

I didn't think this was it because I couldn't get my background image to show up there so I left it thinking it was the wrong place.

Stylesheet_boxes.css is a non-standard, template-specific file. Most templates will not have that, or #column_right or .box_body, but the basic stylesheet.css or possibly other files will control the aspects covered by it.
