Border trouble

[livingstons]

1, I want to put vertical borders between the main body of the site and the background. I want a thin horizontal line to the left and right of the main body before the background.
I have coloured the background yellow to emphasize what I mean, it is going to be white on the finished site hence the need for a dividing border.

2, Also I would like the margin within the main site to be slightly larger so the sideboxes are further away from the horizontal border.

Ok, I sorted it.
As per usual it was simple once I looked in more detail.
