1. 在首页添加显示问答的列表，并定义好相应的样式。

无序列表

<ul >

  <li>Coffee</li>

  <li>Tea</li>

  <li>Milk</li>

</ul>

{% extends'base.html' %}    {% block title %}    首页    {% endblock %}{% block head %}        
         {% endblock %}    {% block main %}        
     
       
      
           
       
用户名:{
   { user }}
           
       
问题:{
   { question }}
           
       
时间:{
   { time }}

2. 用字典向index.html传递参数。
