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。

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"lx3.html" %}
{% block logintitle %}个人中心{% endblock %}
{% block loginhead %}
    <style>
    .nav_ul li{
        list-style: none;
        float: left;
        margin: 10px;
    }
    </style>

{% endblock %}
{% block body %}
<ul class="nav_ul">
<li role="presentation"><a href="{{ url_for('all_question',user_id = username_id) }}">全部问答</a></li>
<li role="presentation"> <a href="{{ url_for('all_comment',user_id = username_id) }}">全部评论</a></li>
<li role="presentation"><a href="{{ url_for('usercenter',user_id = username_id) }}">个人信息</a></li>
</ul>
{% block user %}{% endblock %}

{% endblock %}

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。
4.制作个人中心的三个子页面，重写user.html中定义的user块。

{% extends 'user.html' %}
{% block user %}

    <div class="container">
        <div class="row clearfix">
            <div class="col-md-2 column">

            <div class="col-md-8 column" id="rgba1">
                <p class="text-center">
                    <small>{{ username }}</small>
                </p>
                <hr>
                <h3 align="center">
                    <small>全部问答</small>
                </h3>
                <ul class="list-unstyled">
