一、缩略图
1、概述
通过缩略图组件扩展 Bootstrap 的 栅格系统，可以很容易地展示栅格样式的图像、视频、文本等内容；
如果你想实现一个类似 Pinterest 的页面效果（不同高度和/宽度的缩略图顺序排列）的话，你需要使用一个第三方插件，比如 Masonry、Isotope 或 Salvattore；
2、默认样式的实例
Boostrap 缩略图的默认设计仅需最少的标签就能展示带链接的图片；

二、警告框
警告框组件通过提供一些灵活的预定义消息，为常见的用户动作提供反馈消息；
1、实例
将任意文本和一个可选的关闭按钮组合在一起就能组成一个警告框，.alert 类是必须要设置的，另外我们还提供了有特殊意义的4个类（例如，.alert-success），代表不同的警告信息；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="alert alert-success" role="alert">成功</div>
<div class="alert alert-info" role="alert">信息</div>
<div class="alert alert-warning" role="alert">警告</div>
<div class="alert alert-danger" role="alert">危险</div>
</body>
</html>
运行结果：
2、可关闭的警告框
为警告框添加一个可选的 .alert-dismissible 类和一个关闭按钮；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="alert alert-warning alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">×</span></button>
<strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>
</body>
</html>
运行结果：
备注：
3、警告框中的链接
用 .alert-link 工具类，可以为链接设置与当前警告框相符的颜色；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="alert alert-success" role="alert">
<a href="#" class="alert-link">成功</a>
</div>
<div class="alert alert-info" role="alert">
<a href="#" class="alert-link">信息</a>
</div>
<div class="alert alert-warning" role="alert">
<a href="#" class="alert-link">警告</a>
</div>
<div class="alert alert-danger" role="alert">
<a href="#" class="alert-link">危险</a>
</div>
</body>
</html>
运行结果：
三、进度条
1、概述
通过这些简单、灵活的进度条，为当前工作流程或动作提供实时反馈;
2、基本实例
默认样式的进度条；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
<span class="sr-only">60% Complete</span>
</div>
</div>
</body>
</html>
运行结果：
3、带有提示标签的进度条
将设置了 .sr-only 类的 <span> 标签从进度条组件中移除 类，从而让当前进度显示出来；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
60%
</div>
</div>
</body>
</html>
运行结果：
在展示很低的百分比时，如果需要让文本提示能够清晰可见，可以为进度条设置 min-width 属性：
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
60%
</div>
</div>
<br/>
<br/>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em;">
0%
</div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="2" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em; width: 2%;">
2%
</div>
</div>
</body>
</html>
运行结果：
4、根据情境变化效果
进度条组件使用与按钮和警告框相同的类，根据不同情境展现相应的效果；
代码演示：
<!DOCTYPE html>
<html>
<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></title>
<!-- 引入bootstrap -->
<link rel="stylesheet" href="../css/bootstrap.min.css" />
<!-- 要想实现点击效果，需要引入js -->
<script src="../js/jquery.min.js"></script>
<script src="../js/bootstrap.min.js"></script>
</head>
<body>
<div class="progress">
<div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%">
<span class="sr-only">40% Complete (success)</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
<span class="sr-only">20% Complete</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%">
<span class="sr-only">60% Complete (warning)</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%">
<span class="sr-only">80% Complete (danger)</span>
</div>
</div>
</body>
</html>
运行结果：
5、条纹效果
通过渐变可以为进度条创建条纹效果，IE9 及更低版本不支持；
代码演示：
