How is nosotroshq.com creating the navigation effect when you mouse over a nav item?

Question

Any JQUERY experts know how nosotroshq.com is creating the effect in their top nav? For example, when you mouse over "ABOUT US" it slowly animates down. Any ideas?

Answer 1

Looking at the source, there's actually a second invisible DIV for each button that is offset vertically by one or two pixels and holds the mouseover state image... That div is faded in and out with hover events.

Answer 2

Here i have isolated the menu code! ;-)
