W9 Buttons

I'm sure that's everyone's favourite exercise - styling UI elements for use against pure white background. Buttons are easy, so this is more of a warm up, but styling of input controls is next... brrr.

A is flat
B is gradient
C is gradient + edge (+ cutout)
D is weaker gradient + edges

1 is just button
2 is with drop shadow
3 is with an underlay

Make your pick :)
