One of the most annoying of styling problems that beset the Author recently is to do with inputs. Sure they look pretty after you’re done, but in which browser? Cross-browser compatibility is pretty much impossible for the moment without resorting to a jQuery plugin of some sort.
Of course there’s the argument against styling inputs so that the user knows what everything does and looks the same on whatever site they use. Personally the Author doesn’t agree but each to their own.
Still to make life that little bit easier 456 Berea Street has compiled a collection of screenshots, taken in different browsers of a demo page that shows just how lovely/unsightly things could turn out.
