Rounded corners with CSS (and no images)

I searched a lot to find this great solution for doing rounded borders with just CSS and no images. There are loads of solutions out there which use images to make the borders or doing some funky javascripts which take too much time on page load and the rounding is only applied after onload.

so thanks to Deathshadow for this great solution with pure CSS. just check out the link. there are the examples and the source needed.
