In the administration interface I'm currently using almost completely CSS3 to define the styles of e.g. buttons, text inputs, etc. This looks great for the most part but in most browser which support CSS3 this turns into bad performance.

So I decided to replace some elements with images or make them more simple with not so much box-shadows. But all my tries creating a simple but nice (and scalable!) button using images failed. Can anyone of you out there create such buttons? That would be very great :)
