CSS3 Transitions and borders

[Jankpaymn]

I'm trying to reverse engineer the menu on this web page (this is just a personal project, not trying to steal their work).http://clapat.ro/themes/eleven/color/However, I can't seem to get the transition effect to work. When I add the border-top on, it's pushing the content of the down instead of staying nicely in-line like in the example.Also, the border seems to "blind" upwards, but when I do it, it blinds downwards.Any help would be greatly appreciated!My attempt so far: http://www.guitar-journal.com/monkeydust/index2.php
