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(/blog_article/nt.gif) repeat; } .rbtop div { background: url(/blog_article/tl.gif) no-repeat top left; } .rbtop { background: url(/blog_article/tr.gif) no-repeat top right; } .rbbot div { background: url(/blog_article/bl.gif) no-repeat bottom left; } .rbbot { background: url(/blog_article/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; }
