This is our own take on CSS3 buttons. Our version uses a nice combination of some of the latest CSS3 techniques to produce cool buttons with minimal markup, minimal styling and works across modern browsers.
The cool thing with this design is that each button only has 2 background colors: 1 color for the normal button state, and 1 color for the hover state. The gradient effect you see is just produced by multiple box-shadows on a solid colored background.
