我们写一个基模板,然后让其他的继承.
(1)新建基模板base.html
注意5,13,53行的{%%}块

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>{% block title %}{% endblock %}知了课堂</title>    <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">    <script src="https://cdn.bootcss.com/jquery/3.2.1/core.js"></script>    <script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>    <link rel="stylesheet" href="{{url_for('static',filename = 'css/index.css')}}">    <link rel="stylesheet" href="{{url_for('static',filename = 'css/base.css')}}">    {% block head %}{% endblock %}</head><body>    <nav class="navbar navbar-default">  <div class="container-fluid">    <!-- Brand and toggle get grouped for better mobile display -->    <div class="navbar-header">      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">        <span class="sr-only">Toggle navigation</span>        <span class="icon-bar"></span>        <span class="icon-bar"></span>        <span class="icon-bar"></span>      </button>      <a class="navbar-brand" href="#">        <img class="logo" src="{{url_for('static',filename = 'Logo/cat.png')}}" alt="">      </a>    </div>    <!-- Collect the nav links, forms, and other content for toggling -->    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">      <ul class="nav navbar-nav">        <li class="active"><a href="#">首页 <span class="sr-only">(current)</span></a></li>        <li><a href="#">发布问答</a></li>      </ul>      <form class="navbar-form navbar-left">        <div class="form-group">          <input type="text" class="form-control" placeholder="请输入关键字">        </div>        <button type="submit" class="btn btn-default">搜索</button>      </form>      <ul class="nav navbar-nav navbar-right">        <li><a href="{{url_for('login')}}">登录</a></li>         <li><a href="#">注册</a></li>      </ul>    </div><!-- /.navbar-collapse -->  </div><!-- /.container-fluid --></nav>    <div class="main">        {% block main %}{% endblock %}    </div></body></html>

base.html

.logo{    width: 30px;    height: 30px;}body{    background-color: #f3f3f3;}.main{    background: #fff;    width: 730px;    margin: 0 auto;    overflow: hidden;}

(2)此时index.html可更改如下

{% extends 'base.html' %}{% block title %} 首页 {% endblock %}{% block main %} 这是首页 {% endblock %}

(3)login.html

{% extends 'base.html' %}{% block head %}<link rel="stylesheet" href="{{url_for('static',filename = 'css/login.css')}}">{% endblock %}{% block main %}     <h3 class="page-title">登录</h3>    <form action="" method="post">        <div class="form-container">            <div class="form-group">                <label for="exampleInputEmail1">用户名</label>                <input type="email" class="form-control" id="exampleInputEmail1" placeholder="手机号码">              </div>              <div class="form-group">                <label for="exampleInputPassword1">密码</label>                <input type="password" class="form-control" id="exampleInputPassword1" placeholder="密码">              </div>              <!-- <div class="checkbox">                <label>                  <input type="checkbox"> Check me out                </label>              </div> -->              <button type="submit" class="btn btn-primary btn-block">Submit</button>              </div>    </form>{% endblock %}

index.css

.logo{    width: 30px;    height: 25px;}

.form-container{    width: 300px;    /*将div form-container居中*/    margin: 0 auto;}.page-title{    text-align: center;}.main{    height: 270px;}

注册界面由登录界面作相应更改即可

{% extends 'base.html' %}{% block title %}注册{% endblock %}{% block head %}<link rel="stylesheet" href="{{url_for('static',filename = 'css/login-register.css')}}">{% endblock %}{% block main %}<h3 class="page-title">注册</h3>    <form action="" method="post">        <div class="form-container">            <div class="form-group">                <label for="exampleInputEmail1">手机号码</label>                <input type="email" class="form-control" name='username' placeholder="用户名">              </div>            <div class="form-group">                <label for="exampleInputEmail1">用户名</label>                <input type="text" class="form-control" name="telephone" placeholder="手机号码">              </div>             <div class="form-group">                <label for="exampleInputPassword1">密码</label>                <input type="password" class="form-control" name="password1" placeholder="确认密码">              </div>              <div class="form-group">                <label for="exampleInputPassword1">确认密码</label>                <input type="password" class="form-control" name="password2" placeholder="确认密码">              </div>              <!-- <div class="checkbox">                <label>                  <input type="checkbox"> Check me out                </label>              </div> -->              <button type="submit" class="btn btn-primary btn-block">立即注册</button>              </div>    </form>{% endblock %}

到这一步的时候,把login.css整合了一下,统一成了login-register.css
也就是login.html和register.html共用一个css.
login-register.css如下

.form-container{    width: 300px;    /*将div form-container居中*/    margin: 0 auto;}.page-title{    text-align: center;}.main{    height: 400px;}

不要忘记在主py文件中添加视图函数
最终效果
