徽章（Badges）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:
实例
<h1>示例标题 <span class="badge badge-secondary">New</span></h1>
<h2>示例标题 <span class="badge badge-secondary">New</span></h2>
<h3>示例标题 <span class="badge badge-secondary">New</span></h3>
<h4>示例标题 <span class="badge badge-secondary">New</span></h4>
<h5>示例标题 <span class="badge badge-secondary">New</span></h5>
<h6>示例标题 <span class="badge badge-secondary">New</span></h6>
