解决方案 »

  1.   

    <ul style="list-style:none">
                                 <li><a href="index.aspx" title="查看主题" style="width:160px">查看主题</a></li>
                                 <li><a href="#" title="发表留言" style="width:160px">发表留言</a></li>
                                 <li><a href="#" title="用户注册" style="width:160px">用户注册</a></li>
                                 <li><a href="#" title="我的留言" style="width:160px">我的留言</a></li>
                                 <li><a href="#" title="留言管理" style="width:160px">留言管理</a></li>
                                 <li><a href="#" title="注销登录" style="width:160px">注销登录</a></li>
                               </ul>
      

  2.   

     <link href="" rel="stylesheet" type="text/css"/>看这个CSS 路径对么？改成
     <link href="" rel="stylesheet" type="../text/css"/>
      

  3.   

    <link href="" rel="stylesheet" type="text/css"/>
    是不是这儿忘引用样式表了
    页面上的样式尽量写在外部的CSS里，都写在style不是太好
