1.新页面userbase.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>
2.让userbase.html继承base.html。
重写title,head,main块.
将上述<ul>的样式放在head块，<ul>放在main块中.
定义新的块user。
{% extends "index.html" %} {% block usertitle %}个人中心{% endblock %} {% block userhead %} <style> .nav_ul li{ list-style: none; float: left; margin: 10px; margin-top: 5cm; } </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userbase.html，原个人中心就自动有了标签页导航。
4.制作个人中心的三个子页面，重写userbase.html中定义的user块，分别用于显示问答、评论、个人信息。
{% extends ‘userbase.html‘ %} {% block user %} <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=""> {% for foo in question %} <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="">{{foo.detail}}</p> </li> {% endfor %} </ul> </div> {% endblock %}
{% extends ‘userbase.html‘ %} {% block user %} <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> {% endblock %}
{% extends ‘userbase.html‘ %} {% block user %} <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 %}
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。
