01-往标题中添加徽章

通常在<span>标签添加类badge实现。
示例代码如下：

<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><title>标题中添加徽章</title><meta name="viewport" content="width=device-width,initial-scale=1, shrink-to-fit=no"><link rel="stylesheet" href="bootstrap-4.5.3-dist/css/bootstrap.css"><script src="jquery-3.5.1.slim.js"></script><script src="bootstrap-4.5.3-dist/js/bootstrap.min.js"></script>
</head>
<body class="container">
<h3 align="center">标题中添加徽章</h3>
<h1>标题1 <span class="badge badge-secondary">徽章</span></h1>
<h2>标题2 <span class="badge badge-secondary">徽章</span></h2>
<h3>标题3 <span class="badge badge-secondary">徽章</span></h3>
<h4>标题4 <span class="badge badge-secondary">徽章</span></h4>
<h5>标题5 <span class="badge badge-secondary">徽章</span></h5>
<h6>标题6 <span class="badge badge-secondary">徽章</span></h6>
