  <br />
  <div class="content"><a href="http://www.chinayabisi.com" target="_blank">http://www.chinayabisi.com</a></div>
</div>
</body>
</html>

说明：

#shade的高度设置的大一些就可以遮罩整个页面
以下代码放置在body 开始位置 就可以在页面居中，不居中自己再调试一把吧

<div id="Layer1">
  <div id="win_top">雅比斯 - 我的个人代码库 <a href="#" onClick="shade.style.display='none';Layer1.style.display='none'">关闭</a></div>
  <br />
  <div class="content"><a href="http://www.chinayabisi.com" target="_blank">http://www.chinayabisi.com</a></div>
