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 %} <script src="{{url_for(‘static‘,filename=‘js/base.js‘) }}" type="text/javascript"></script> <link href="{{ url_for(‘static‘ ,filename=‘css/base.css‘) }}" rel="stylesheet" type="text/css"> {% endblock %} {% block main %} </head> <body id="myBody"> <div id="gufeng"> <ul class="list" > <li class="">用户名:{{ user }}</li> <li class="">问题:{{ question }}</li> <li class="">时间:{{ time }}</li> </ul> </div> <footer> <div class="footer_box"> Copyright@2017-2027 个人版权，版权所有 作者：JZX telephone:0000-1234567 mobile phone:11111111111 </div> </footer> {% endblock %} </body> </html>
