1、所有可用的图标：
包括250多个来自 Glyphicon Halflings 的字体图标。Glyphicon Halflings 一般是收费的，但是他们的作者允许 Bootstrap 免费使用。（https://v3.bootcss.com/components/）
<button type="button" class="btn btn-default btn-lg"> <span class="glyphicon glyphicon-star" aria-hidden="true"></span> Star </button>
2、下拉菜单：
<!DOCTYPE html> <html> <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入门</title> <link href="../css/bootstrap.min.css" rel="stylesheet"> <script src="../js/jquery-1.11.3.min.js"></script> <script src="../js/bootstrap.js"></script> <![endif]--> </head> <body> <div class="dropdown"> <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true"> 我是一个下拉菜单 <span class="caret"></span> </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenu1"> <li><a href="#">甜点</a></li> <li><a href="#">午餐</a></li> <li><a href="#">晚餐</a></li> <li role="separator" class="divider"></li> <li><a href="#">蔬菜</a></li> </ul> </div> </body> </html>
