Rounded Corners Using CSS

b.rtop, b.rbottom{display:block;background: #FFF}
b.rtop b, b.rbottom b{display:block;height: 1px; overflow: hidden; background: #ddd}
b.r1{margin: 0 5px}
b.r2{margin: 0 3px}
b.r3{margin: 0 2px}
b.rtop b.r4, b.rbottom b.r4{margin: 0 1px;height: 2px}

My pal Ben Simon sent me this URL a while ago that describes a technique for creating rounded corners using just CSS and no images. Check out Nifty Corners for the full scoop. Hopefully you are
looking at an example right now, unless it doesn’t work in your
browser for some reason (I haven’t done extensive testing). If it
doesn’t work, leave a comment here so people will know the compatibility
limitations.

Update: I have no idea why this wouldn’t work in IE. An isolated version of the code works fine as do the examples. I suspect it’s just buggy IE rendering, but if anyone can figure out why it’s not working, and can suggest a fix, I will publicly shower him or her with praise.
