A Flash Blue Menu
A simple menu that uses CSS3 keyframes property to create a flashy effect. Initially, the menu is given a gray color and when it is hovered, the color changes instantly to a very light bluish gray color and then to a dark blue color over a period of 200ms.
Also, the menu has a very cool active state. Clever use of box-shadow to give it a "indent / pressed" look. Works in Firefox, Chrome and Safari as other browsers don't support animation and keyframes properties yet.
