rounded corner for box styles in XHTML / CSS

Today I found a cool generator for rounded box layouts which is pretty simple to use. You only have to define your colors and click the button. You get all sources to create pretty rounded css boxes :-)

Simple and greate: http://www.neuroticweb.com/recursos/css-rounded-box/index.php

Css:
/* set millions of background images */
.rbroundbox { background: url(nt.gif) repeat; }
.rbtop div { background: url(tl.gif) no-repeat top left; }
.rbtop { background: url(tr.gif) no-repeat top right; }
.rbbot div { background: url(bl.gif) no-repeat bottom left; }
.rbbot { background: url(br.gif) no-repeat bottom right; }
/* height and width stuff, width not really nessisary. */
.rbtop div, .rbtop, .rbbot div, .rbbot {width: 100%;height: 7px;font-size: 1px;}
.rbcontent { margin: 0 7px; }.rbroundbox { width: 50%; margin: 1em auto; }

HTML:

<div class="rbroundbox">

<div class="rbtop"><div></div></div>

<div class="rbcontent">
