block 后面是给区域起的名字
继承母板
1、先继承模板的所有的内容
2、根据block块的名字修改指定区域的内容
{% extends 'home.html' %} {% block content %} <h1>登录页面</h1>
<form action=""> <p>username:<input type="text" class="form-control"></p> <p>password:<input type="text" class="form-control"></p> <input type="submit" class="btn btn-success"> </form> {% include 'hualihushao.html' %} {% endblock %}
如果还想用以前的 只需要在上面代码的 《登录页面》下面加
{{block.super}}
通常情况下一个模板至少有三块 1、 页面CSS代码 2、页面JS代码块 3、页面的主体内容
导入（写‘死’的内容适合用）
{% include '想导入的HTML文件名'%}
