Bootstrap是Twitter 开发的一个开源框架，可以创建简洁有吸引力的网页。简单测试一下

安装：

pip install flask-bootstrap

注：需要提前在程序运行目录下创建templates文件夹，另外新建user.html

文件结构图：

test.py，页面处理

from flask import Flask, render_template

app=Flask(__name__)
# ...
@app.route('/')
def index():
    return render_template('index.html')

@app.route('/user/<name>')
def user(name):
    return render_template('user.html', name=name)

test1.py，引入框架

from  flask_bootstrap import Bootstrap
from test import app



bootstrap = Bootstrap(app)

#运行
app.run()

user.html，页面

{% extends "bootstrap/base.html" %}
{% block title %}Flasky{% endblock %}
{% block navbar %}
<div class="navbar navbar-inverse" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle"
            data-toggle="collapse" data-target=".navbar-collapse">
            <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="/" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow" >Flasky</a>
        </div>
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li><a href="/" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow" >Home</a></li>
            </ul>
        </div>
    </div>
</div>

{% endblock %}
{% block content %}
<div class="container">
    <div class="page-header">
        <h1>Hello, {{ name }}!</h1>
    </div>
</div>
{% endblock %}
