Bootstrap是Twitter推出的一个用于前端开发的开源工具包。而Flask-Bootstrap就是利用了Bootstrap来编写了一个Jinja2的模版，通过extends include block基于这个模版来替换成你自己的内容；
注册到Flask中
from flask import Flask
from flask_bootstrap import Bootstrap
app = Flask(__name__)
bootstrap = Bootstrap(app)
或
from flask import Flask
from flask_bootstrap import Bootstrap
def create_app():
app = Flask(__name__)
Bootstrap(app)
return app
简单的模版
{% extends "bootstrap/base.html" %}
{% block title %}This is an example page{% endblock %}
{% block navbar %}
<div class="navbar navbar-fixed-top">
<!-- ... -->
</div>
{% endblock %}
{% block content %}
<h1>Hello, Bootstrap</h1>
{% endblock %}
ps: 若在pycharm IDE中extends bootstrap not found时，请将templates文件夹 Make directory as --> template
