Such a nice style of CSS buttons that I found on ZURB. They created beautiful CSS web buttons in multiple color and give you free code for using for you web. You can learn how to create CSS web button using CSS3 by your own from their sample code, learn some techniques or just copy and paste the code on your web.
You can change color of the button to your favorite color by just change the color of RGBA Hex color and you can also change the size of the button freely.
The buttons are beautiful and good for all web designers, you can view demo from this link.
