Bootstrap 5教程

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）：

实例

<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>

上下文徽章

请使用任意上下文类 (.bg-*) 来更改徽章的颜色：

实例

<span class="badge bg-primary">主要</span>
<span class="badge bg-secondary">次要</span>
<span class="badge bg-success">成功</span>
<span class="badge bg-danger">危险</span>
<span class="badge bg-warning">警告</span>
<span class="badge bg-info">信息</span>
<span class="badge bg-light">浅色</span>
<span class="badge bg-dark">深色</span>

胶囊徽章

使用 .rounded-pill 类使徽章更圆润：

实例

<span class="badge rounded-pill bg-primary">主要</span>
<span class="badge rounded-pill bg-secondary">次要</span>
<span class="badge rounded-pill bg-success">成功</span>
<span class="badge rounded-pill bg-danger">危险</span>
<span class="badge rounded-pill bg-warning">警告</span>
<span class="badge rounded-pill bg-info">信息</span>
<span class="badge rounded-pill bg-light">浅色</span>
<span class="badge rounded-pill bg-dark">深色</span>

元素内的徽章

在按钮内使用徽章的例子：

实例

<button type="button" class="btn btn-primary">
  消息 <span class="badge bg-danger">4</span>
</button>
