I recently tweaked the Twenty Eleven theme a lot to make it work for my restaurant client and recently we had to introduce a drop-down ul li menu to the mix. I wanted to give it a 1 pixel solid border, which I did to the #access ul li:hover > ul element but it only worked to a point. Try this, go to the homepage of this siteand rollover MENUS to see what's going on. You can't really see it, but the border it only rendering on the top of the element. It should of course, go all the way around the element. How do I make that work so the border appears as it should?
