<p>仿淘宝网站的导航效果。此方法有几个优点:</p>
    
<ul>
      
<li>根据字数自适应项目长度</li>
      
<li>不同的项目使用不同的颜色来区分</li>
      
<li>无需使用脚本</li>
      
<li>背景图片只需要两个图片文件就足够,减少服务器负担<br />
       这是使用到的两个图片:
         
<table width="58%" border="1" cellspacing="2" cellpadding="0">
           
<tr>
             
<td width="70%" align="center"><img src="http://pics.taobao.com/2k5/sys/component/tab_selected_left_bk2.gif" width="250" height="290" /></td>
             
<td width="30%" align="center"><img src="http://pics.taobao.com/2k5/sys/component/tab_selected_right_bk2.gif" width="15" height="290" /></td>
           
</tr>
         
</table>
