Bootstrap 5 徽章
徽章
徽章（Badges）用于向内容添加附加信息：
在 <span> 元素中使用 .badge 类和上下文类（如 .bg-secondary）来创建矩形徽章。请注意，徽章会缩放以匹配父元素的大小（如果有）：
示例代码：
<h1>Example heading <span class="badge bg-secondary">New</span></h1>
<h2>Example heading <span class="badge bg-secondary">New</span></h2>
<h3>Example heading <span class="badge bg-secondary">New</span></h3>
<h4>Example heading <span class="badge bg-secondary">New</span></h4>
<h5>Example heading <span class="badge bg-secondary">New</span></h5>
<h6>Example heading <span class="badge bg-secondary">New</span></h6>
