Tired of messing around with image files to create tasteful (and expandable) button graphics? Why don’t you just use some CSS3 techniques to build them on the fly? Smashing Magazine’s Pushing Your Buttons With Practical CSS3 describes how to use box-shadow, text-shadow, and border-radius to create buttons out of pure CSS. Then they take things a little further with some animated WebKit glow effects.
Oh, and the article also shows how to create the custom buttons that Google uses for WebKit browsers.
What would be do without Smashing Magazine?
