1. 新頁面user.html,用<ul ><li role="presentation"> 實現標籤頁導航。
   <ul class="nav nav-tabs">
     <li role="presentation"><a href="#">Home</a></li>
     <li role="presentation"><a href="#">Profile</a></li>
     <li role="presentation"><a href="#">Messages</a></li>
   </ul>
   

   <ul class="nav_ul">
           <li role="presentation"><a href="#">所有問答</a></li>
           <li role="presentation"><a href="#">所有評論</a></li>
           <li role="presentation"><a href="#">我的信息</a></li>
       </ul>

    

2. user.html繼承base.html。
   重寫title,head,main塊.
   將上述<ul>放在main塊中.
   定義新的塊user。
   

   {% extends 'base.html' %}
   {% block title %}我的中心{% endblock %}
   {% block head %}
       <style>
           .nav_ul li {
               list-style: none;
               float: left;
               margin: 30px;
           }
       </style>
   {% endblock %}
   
   {% block main %}
       <ul class="nav_ul">
       <li role="presentation"><a href="#">所有問答</a></li>
       <li role="presentation"><a href="#">所有評論</a></li>
       <li role="presentation"><a href="#">我的信息</a></li>
       </ul>
   
       {% block user %}{% endblock %}
   {% endblock %}

    

3. 讓上次做業完成的我的中心頁面，繼承user.html，原我的中心就自動有了標籤頁導航。
   
   
4. 製做我的中心的三個子頁面，重寫user.html中定義的user塊。
   

   {% extends 'user.html' %}
   {% block title %}我的中心 {% endblock%}
   {% block main%}
    
   <div class="page-header">
       <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>
       {{username}} <br> <small>所有問答><span class="badge"></span> </small></h3>
       <ul class="list-group" style="">
           {% for foo in user.question %}
               <li class="list-group-item">
                   <spanclass="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                   <a href="#">{{foo.author.username }}</a>
                   <spanclass="badge">{{foo.creat_time}}</span>
                   <p style="">{{foo.detail}}</p>
               </li>
       {% endfor %}
       </ul>
   </div>
    
   <div class="page-header">
        <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>
       {{user}} <br> <small>person information><span class="badge"></span> </small></h3>
       <ul class="list-group" style="">
             {% for foo in user.comments %}
               <li class="list-group-item">
                   <spanclass="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                   <a href="#">{{foo.author.username }}</a>
                   <spanclass="badge">{{foo.creat_time}}</span>
                   <p style="">{{foo.detail}}</p>
               </li>
       {% endfor %}
       </ul>
   </div>
    
   <div class="page-header">
        <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>
       {{user}} <br> <small>person information><span class="badge"></span> </small></h3>
         <ul class="list-group" style="">
             <li class="list-group-item">username：{{username}}</li>
             <li class="list-group-item">number：</li>
             <li class="list-group-item">nicheng：</li>
             <li class="list-group-item">new page：</li>
         </ul>
   </div>
    
   {% endblock %}

    

5. 思考 如何實現點標籤頁導航到達不一樣的我的中心子頁面。
