Bootstrap中任何带有 class .btn 的元素都会继承圆角灰色按钮的默认外观，再结合一些选项，可以定义各种按钮样式。

0x03 其他按钮

移动端一个按钮占用一行按钮，可以利用.btn-block类来实现块状按钮。Bootsrap通过将announce背景色设置为50%褪色的方式来呈现无法点击的效果：

<!DOCTYPE html>
<html lang="zh-cn">
<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link href="../../css/bootstrap.min.css" rel="stylesheet">
 <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
 <script src="../../js/bootstrap.min.js"></script>
 <title>其他按钮</title>
</head>
<body>
<div class="container">
 <div class="page-header">
 <h1>其他按钮</h1>
 </div>
 <div>
 <p>
 <button type="button" class="btn btn-block btn-success">Block</button>
 </p>
 <p>
 <button type="button" class="btn btn-lg btn-default" disabled="disabled">不可用按钮1</button>
 <a href="#" class="btn btn-lg btn-info disabled">不可用按钮2</a>
 </p>
 </div>
</div>
</body>
