徽章
1. 徽章（.Badges）
徽章主要用于突出显示新的或未读的项。如需使用徽章，只需要将 .badge 类加上带有指定意义的颜色类 (如 .badge-secondary) 添加到 < span > 元素上即可。 徽章可以根据父元素的大小的变化而变化。
代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" />
<script src="js/jquery.slim.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/popper.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/bootstrap.min.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="container">
<h1>测试标题 <span class="badge badge-secondary">New</span></h1>
<h2>测试标题 <span class="badge badge-secondary">New</span></h2>
<h3>测试标题 <span class="badge badge-secondary">New</span></h3>
<h4>测试标题 <span class="badge badge-secondary">New</span></h4>

进度条可以显示用户任务的完成过程。
创建进度条步骤如下：
1. 添加一个带有 .progress 类的 < div >。
2. 然后在上面的 < div > 内，添加一个带有 class .progress-bar 的空的 < div >。
3. 添加一个带有百分比表示的宽度的 style 属性，例如 style=“width:70%” 表示进度条在 70% 的位置。
代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" />
