在Bootstrap中使用.label-danger类添加红色标签。
您可以尝试运行以下代码来实现.label-danger 类-
<!DOCTYPE html> <html> <head> <title>Bootstrap Example</title> <link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet"> <script src = "/scripts/jquery.min.js"></script> <script src = "/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div class = "container"> <p>If you find any issues, click below</p> <span class = "label label-danger">Danger</span> </div> </body> </html>
