定义和使用
徽章用于将附加信息添加到任何内容;在<span>元素中将 .badge 类与上下文类(例如.badge-secondary)一起使用,以创建矩形标记。请注意,徽章会缩放以匹配父元素的大小(如果有):
尝试一下<div class="container"> <h1>标题内容 <span class="badge badge-secondary">New</span></h1> <h2>标题内容 <span class="badge badge-secondary">New</span></h2> <h3>标题内容 <span class="badge badge-secondary">New</span></h3> <h4>标题内容 <span class="badge badge-secondary">New</span></h4> <h5>标题内容 <span class="badge badge-secondary">New</span></h5> <h6>标题内容 <span class="badge badge-secondary">New</span></h6> </div>
输出结果如下:标题内容 New标题内容 New标题内容 New标题内容 New标题内容 New标题内容 New -
