Bootstrap入门一：Hello Bootstrap

一、Bootstrap简介

Bootstrap，来自 Twitter，是目前很受欢迎的前端框架。Bootstrap是基于 HTML5、CSS3和Javascriopt开发的，它在 jQuery的基础上进行了更为个性化和人性化的完善，形成一套自己独有的网站风格，并兼容大部分jQuery插件，为实现快速开发提供了一套前端工具包，包括丰富的布局、栅格、丰富的Web组件和jQuery插件等，并能通过Less进行样式定制。

二、Hello Bootstrap

1.建立项目目录结构，新建app、css、font、img和js目录，其中app存放angular相关子模板和控制器。向css目录中拷贝入ie10-viewport-bug-workaround.css，向js目录中拷贝入ie8-responsive-file-warning.js、ie-emulation-modes-warning.js和ie10-viewport-bug-workaround.js，这几个文件是让bootstrap在ie浏览器中针对ie的兼容性做的优化。

2.新建index.html页面，在中引入bootstrap.css及兼容ie的css：

3.在底部依次引入jquery.js、bootstrap.js及兼容ie的js：

4.编写页面内容，先在标签下加入<div class="container"></div>,然后在其中插入具体页面代码，本例包括顶部导航和一个，完整代码如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="description" content="">
    <meta name="author" content="Mac.Manon">
    <link rel="icon" href="../../favicon.ico">
