个人中心标签页导航

1. 新页面user.html,用<ul ><li role="presentation"> 实现标签页导航。
   <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="#">questions</a> </li>
       <li role="presentation"><a href="#">comments</a> </li>
       <li role="presentation"><a href="#">information</a> </li>
   </ul>
   

   　　

2. user.html继承base.html。
   重写title,head,main块.
   将上述<ul>放在main块中.
   定义新的块user。

   {% extends "myweb.html" %}
   {% block usertitle %}个人中心{% endblock %}
   {% block userhead %}
       <style>
           .nav_ul li{
               list-style: none;
               float: left;
               margin: 10px;
           }
       </style>
   {% endblock %}
   
   {% block mywebbody %}
   <ul class="nav_ul">
       <li role="presentation"><a href="#">questions</a> </li>
       <li role="presentation"><a href="#">comments</a> </li>
       <li role="presentation"><a href="#">information</a> </li>
   </ul>
   
   {% block usercenterbody %}{% endblock %}
   
   {% endblock %}
   
   </html>
   

   　　

   
   
   
3. 让上次作业完成的个人中心页面，继承user.html，原个人中心就自动有了标签页导航。
   

   {% extends "user.html" %}
   
   {% block usercenterbody %}
       <div class="page-header">
           <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ username }}<br><small>全部问答<span class="badge>"></span> </small> </h3>
           <ul class="list-group"style="margin:10px">
               {% for foo in comments %}
                   <li class="list-group-item">
                       <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                       <a href="#">{{ foo.author.username }}</a>
                       <span class="badge">{{ foo.creat_time }}</span>
                       <p style="align-content: center">{{ foo.detail }}</p>
                   </li>
               {% endfor %}
           </ul>
       </div>
   
       <div class="page-header">
           <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ user }}<br><small>全部评论<span class="badge>"></span> </small> </h3>
           <ul class="list-group"style="margin:10px">
               {% for foo in comments %}
                   <li class="list-group-item">
                       <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                       <a href="#">{{ foo.author.username }}</a>
                       <span class="badge">{{ foo.creat_time }}</span>
                       <p style="align-content: center">{{ foo.detail }}</p>
                   </li>
               {% endfor %}
           </ul>
   
       </div>
   
       <div class="page-header">
           <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span>{{ user }}<br><small>个人信息<span class="badge>"></span> </small> </h3>
           <ul class="list-group"style="margin:10px">
               <li class="list-group-item">用户：{{ username }}</li>
               <li class="list-group-item">编号：</li>
               <li class="list-group-item">昵称：</li>
           </ul>
       </div>
   {% endblock %}
   

   　　

4. 制作个人中心的三个子页面，重写user.html中定义的user块。
   
   
5. 思考 如何实现点标签页导航到达不同的个人中心子页面。
