I have implemented rounded corners for html elements as it is written in this article (final result of that article you can see here). Everything was ok, but! it doesn't work in Opera browser. While Opera developers say that their browser has the best of all support for clip CSS properties and for SVG.
Please help, what is the problem in that example? (mime types, svg version, etc.?)
Thanks.
The answer so far is "no. You can't.". It is a recorded bug in Opera Bugs DB.
SVG is one possible hack, there is a tool for rounded corners to help you get it right
