See here for code: http://jsfiddle.net/9pezn/
I know how to do the position bottom, negative margin trick with a bottom-border to make a hovered/active “tab” z-index over it but have been unable to recreate this effect when using a box-shadow. Any ideas?
I.E. I want the main navigation tabs to be on top of the box-shadow! I am essentially attempting to replicate what the Nike.com navigation does. E.g. When you hover over “Sports,” then the bottom shadow is covered.
Thanks in advance!

I found a solution I’m willing to settle for: http://jsfiddle.net/LVppY/
Scott, you were on the right track that it could be done with z-index
