用url_for加载静态文件

flask 从static文件夹开始寻找

可用于加载css, js, image文件

继承和扩展

把一些公共的代码放在父模板中，避免每个模板写同样的内容。base.html

子模板继承父模板

1. 1. {% extends \'base.html’ %}

父模板提前定义好子模板可以实现一些自己需求的位置及名称。block

1. 1. <title>{% block title %}{% endblock %}-MIS问答平台</title>
  2. {% block head %}{% endblock %}
  3. {% block main %}{% endblock %}

子模板中写代码实现自己的需求。block

{% block title %}登录{% endblock %}

首页、登录页、注册页都按上述步骤改写。
