What’s this that works on IE and any other browser, except on Opera?!
That was a strange answer. Who’s making rounded corners with CSS?! on IE and more important how? There is a way to make it, but not entirely with CSS and HTML. The solution is with VML a subset of XML to deal with vectors, and CSS of course.
The original solution I found on snook.ca.
It is really working fine as described and shown in the example, but there are some issues as well. There is no way to setup background image on the container, and the width and height are behaving strange.
However this gives you an opportunity to make cross browser rounded corners with no scripting that slows down the page and except Opera it’s quite working!
