将上面生成的图片和下面代码存在同一个文件夹下：

CSS圆角区块容器.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; }
