I made a HTML app that use border-image.
Chrome always updates automatically, and FireFox support -moz-border-image since 3.5+. So I think it’s safe to say that most Chrome and FireFox user can enjoy the effect. But for IE user, I also want them to enjoy a less enjoyable, but tolerable effect.
Therefore, I think I need a proper way to find whether the browser support border-image using JavaScript and do some hack, and I don’t know how to do this.
