首先引入bootstrap官网链接:http://www.bootcss.com/
bootstrap 3下载地址:http://v3.bootcss.com/getting-started/#download
bootstrap的CDN链接:
<!-- 新 Bootstrap 核心 CSS 文件 --> <link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css"> <!-- 可选的Bootstrap主题文件(一般不用引入) --> <link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap-theme.min.css"> <!-- jQuery文件。务必在bootstrap.min.js 之前引入 --> <script src="//cdn.bootcss.com/jquery/1.11.3/jquery.min.js"></script> <!-- 最新的 Bootstrap 核心 JavaScript 文件 --> <script src="//cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
使用bootstrap的基本模板
<!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"> <!-- 上述3个meta标签*必须*放在最前面,任何其他内容都*必须*跟随其后! --> <title>Bootstrap 101 Template</title> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet"> <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries --> <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> <!--[if lt IE 9]> <script src="//cdn.bootcss.com/html5shiv/3.7.2/html5shiv.min.js"></script> <script src="//cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script> <![endif]--> </head> <body> <h1>你好,世界!</h1> <!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> <script src="//cdn.bootcss.com/jquery/1.11.3/jquery.min.js"></script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="js/bootstrap.min.js"></script> </body> </html>
分步解析bootstrap模板
<!--网页编码格式--> <meta charset="utf-8"> <!--在IE运行最新的渲染模式--> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <!--初始化移动设备浏览显示--> <!--width=device-width宽度等于设备宽度--> <!--initial-scale=1初始缩放比例为1--> <meta name="viewport" content="width=device-width, initial-scale=1"> <!--这一块是对IE8和9的一些支持--> <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries --> <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> <!--[if lt IE 9]> <script src="//cdn.bootcss.com/html5shiv/3.7.2/html5shiv.min.js"></script> <script src="//cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script> <![endif]-->
最后注意:
一般css放在head中,jQuery的引用和js文件放在body的最下面。
