徽章通常用于在网页上指示一些有价值的信息,例如重要的标题,警告消息,通知计数器等。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:
<!DOCTYPE html> <html> <head> <title>Bootstrap 示例</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css"> <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script> <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script> <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script> </head> <body> <div class="container"> <h2>徽章</h2> <h1>Bootstrap heading <span class="badge badge-secondary">New</span></h1> <h2>Bootstrap heading <span class="badge badge-secondary">New</span></h2> <h3>Bootstrap heading <span class="badge badge-secondary">New</span></h3> <h4>Bootstrap heading <span class="badge badge-secondary">New</span></h4> <h5>Bootstrap heading <span class="badge badge-secondary">New</span></h5> <h6>Bootstrap heading <span class="badge badge-secondary">New</span></h6> </div> </body> </html>测试看看 ‹/›
