什么是Bootstrap?
Bootstrap是一个web框架。Bootstrap,来自 Twitter,是目前很受欢迎的前端框架。Bootstrap 是基于 HTML、CSS、JAVASCRIPT 的,它简洁灵活,使得 Web 开发更加快捷。 它由Twitter的设计师Mark Otto和Jacob Thornton合作开发,是一个CSS/HTML框架。Bootstrap提供了优雅的HTML和CSS规范,它即是由动态CSS语言Less写成。Bootstrap一经推出后颇受欢迎,一直是GitHub上的热门开源项目,包括NASA的MSNBC(微软全国广播公司)的Breaking News都使用了该项目。国内一些移动开发者较为熟悉的框架,如WeX5前端开源框架等,也是基于Bootstrap源码进行性能优化而来。
如何获取Bootstrap:
从http://v3.bootcss.com/网站下载bootstrap。
将下载的压缩包解压后将下列3哥文件夹拷贝到D盘的的bootsrap-01文件夹下:
注意:Bootstrap是基于jQuery的,所以js文件夹里还要放入一个jQuery文件,下载地址:http://jquery.com/
然后新建一个pages文件夹(用于放编写的html文件),里面新建一个Demo.html文件,,用编辑器打开,写入如下代码:
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Bootstrap Demo</title> <!-- Bootstrap CSS --> <link href="../css/bootstrap.min.css" rel="stylesheet"> <!-- Bootstrap javascript --> <script type="text/javascript" src="../js/jquery-3.2.1.js"></script> <script type="text/javascript" src="../js/bootstrap.min.js"></script> <script type="text/javascript"> </script> <style type="text/css"> .frame { margin: 0 auto; width: 1000px; height: 100%; } </style> </head> <body> <div class="frame"> <!-- Bootstrap 警告框 --> <div class="alert alert-success" role="alert">Well done!

执行效果如下:
总结:Bootstrap框架给我的印象就是非常大方、简介、漂亮、易上手,希望小伙伴们好好学,该框架是目前公司里非常流行的一种框架。
