CSS3 Button is a simple page button completely styled in CSS (no images).
It has 6 styles of buttons in seven different colors.
COLORS: green, yellow, orange, red, pink, black, silver
STYLES: square, round, skewed, square with gradient, round with gradient and skewed with gradient.
Note: The font in the screenshot-examples is 'Orbitron' and placed with use of Cufón. The CSS3 button addon works just fine without those!!
Cufón and the Orbitron font is not included in this block. Cufón is here. Orbitron can be found in Google web fonts
1.1 Update: Added possibility to link to an external url.
