Rounded Corners

Historically rounded corners were tricky to implement involving a background graphic or even JavaScript. Interface designers would issue a little sigh as designers littered designs with rounded corners. Well not any more!

Corners for all

Now you can create rounds corners easily using CSS. There is a bit of variance between browser vendors at the moment but I imagine eventually the syntax will standardise. To add rounded corners you just need:

/* Gecko browsers */
-moz-border-radius: 5px;
/* Webkit browsers */
-webkit-border-radius: 5px;
/* W3C syntax - likely to be standard so use for future proofing */
border-radius:10px;

/* Gecko browsers */
-moz-border-radius-topleft: 20px;
-moz-border-radius-topright: 0;
-moz-border-radius-bottomleft: 0;
-moz-border-radius-bottomright: 20px;

/* Webkit browsers */
-webkit-border-top-left-radius: 20px;
-webkit-border-top-right-radius: 0;
-webkit-border-bottom-left-radius: 0;
-webkit-border-bottom-right-radius: 20px;

/* W3C syntax */
border-top-left-radius: 20px;
border-top-right-radius: 0;
border-bottom-right-radius: 0;
border-bottom-left-radius:  20px;
