Bootstrap5 徽章（Badges）

2023-06-25 15:23 更新

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 .bg-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:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>徽章</h2>
  <h1>测试标题 <span class="badge bg-secondary">New</span></h1>
  <h2>测试标题 <span class="badge bg-secondary">New</span></h2>
  <h3>测试标题 <span class="badge bg-secondary">New</span></h3>
  <h4>测试标题 <span class="badge bg-secondary">New</span></h4>
  <h5>测试标题 <span class="badge bg-secondary">New</span></h5>
  <h6>测试标题 <span class="badge bg-secondary">New</span></h6>
</div>

</body>
</html>

各种颜色类型的徽章

以下列出了所有颜色类型的徽章:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>各种颜色类型的徽章</h2>
  <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>
</div>

</body>
</html>

药丸形状徽章

使用 .rounded-pill 类来设置药丸形状徽章:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>药丸形状徽章</h2>
  <span class="badge rounded-pill bg-default">默认</span>
  <span class="badge rounded-pill bg-primary">主要</span>
  <span class="badge rounded-pill bg-success">成功</span>
  <span class="badge rounded-pill bg-info">信息</span>
  <span class="badge rounded-pill bg-warning">警告</span>
  <span class="badge rounded-pill bg-danger">危险</span>
</div>

</body>
</html>

徽章插入到元素内

以下实例将徽章嵌入到按钮内：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>徽章嵌入到按钮内</h2>
  <button type="button" class="btn btn-primary">
    Messages <span class="badge bg-danger">4</span>
  </button>
  <button type="button" class="btn btn-danger">
    Notifications <span class="badge bg-dark">7</span>
  </button>
</div>

</body>
</html>
