刚开始通过绝对路径尝试了好多次都看不到bootstrap
在这里需要说一下，bootstrap的js是依赖于jquery的，所以在引入bootstrap的js文件前 需要先引入jquery
我这里是通过引入在线文件来实现的。
首先创建了一个html文件：
代码如下：
<!DOCTYPE html><html><head> <meta charset="utf-8"> <title>Bootstrap 实例 - 响应式的列重置</title> <link rel="stylesheet" href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script> <script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script></head><body><div class="container"> <div class="row" > <div class="col-xs-6 col-sm-3" style="background-color: #dedef8; box-shadow: inset 1px -1px 1px #444, inset -1px 1px 1px #444;"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p> </div> <div class="col-xs-6 col-sm-3" style="background-color: #dedef8;box-shadow: inset 1px -1px 1px #444, inset -1px 1px 1px #444;"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Ut enim ad minim </p> </div> </div></div> <h2>图标</h2> <p>插入图标:</p> <p>云图标: <span class="glyphicon glyphicon-cloud"></span></p> <p>信件图标: <span class="glyphicon glyphicon-envelope"></span></p> <p>搜索图标: <span class="glyphicon glyphicon-search"></span></p> <p>打印图标: <span class="glyphicon glyphicon-print"></span></p> <p>下载图标：<span class="glyphicon glyphicon-download"></span></p> </body></html>
显示结果：
