CSS Button Style: Draped Background Effect
Author: Dynamic Drive
These CSS buttons are endowed with a partially transparent background that
"drapes" into view when the mouse rolls over them, creating a sleek, polished
look. The "drape" is rendered using a
:after pseudo element with
rounded corners that glide into view thanks to CSS3 transitions.
This button style can be applied to BUTTON or A elements to style either depending on your needs.
