Thanks, that worked well for one site. Now I'm on to another and want to have no background for the bottom, right, and left of the menu.
This one is a bit more complicated because the menu has a gradient background, and there is a shadow bg image underneath the menu. So setting the borders to the same color as background won't work in this case.
Here's the blog:
It needs to look like this:
When I try to remove the side borders like you showed me in your reply it removes the right one, but the left one still has 1px. It looks like before removeing them the right border is doubled for some reason...
Not sure how to remove the bottom border, or if that's too complicated...
