Look towards the bottom, "Browser Compatibility"

It's not supported in every browser on the planet, but quite a lot of browsers does support it. Use this code:

#your_box {
border: 1px solid black; /*the box NEEDS to have a border for this to work. The border color can be the same as the background-color.*/
-moz-border-radius: 30px;
-webkit-border-radius: 30px;
border-radius: 30px;
}

AFAIK this is supported in Firefox, Safari, Google Chrome and Opera. Don't know about the other browsers.

The only "other browser" that doesn't support this is IE, the world's worst browser. But that's to be expected.

@drhowarddrfine :
There are more browsers out there than Safari, Google Chrome, Firefox, Opera and Internet Explorer. Also, as of IE9, IE supports border-radius. (Source: http://stackoverflow.com/questions/6...r-radius-in-ie).

[drhowarddrfine]

Yes, but 98% of all browsers used are one of those.

IE9 isn't out yet and is a poor choice for anyone since it will be the worst in supporting modern standards and practices in most areas.
