Border-radius: create rounded corners with CSS!

W3C has offered some new options for borders in CSS3, of which one is border-radius. Both Mozila/Firefox and Safari 3 have implemented this function, which allows you to create round corners on box-items. This is an example:

Mozilla/Firefox and Safari 3 users should see a nicely rounded box, with a nicely rounded border.

The code for this example above is actually quite simple:

<div style=" background-color: #ccc;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
border: 1px solid #000;
padding: 10px;" >

These different corners can also each be handled on their own, Mozilla has other names for the feature than the spec says it should have though, as it has f.i. -moz-border-radius-topright as opposed to -webkit-border-top-right-radius:

Mozilla/Firefox and Safari 3 users should see a box with a rounded left upper corner.

Mozilla/Firefox and Safari 3 users should see a box with a rounded right upper corner.

Mozilla/Firefox and Safari 3 users should see a box with a rounded left lower corner.

Mozilla/Firefox and Safari 3 users should see a box with a rounded right lower corner.
