将<span class =“ badge”>放置到活动链接，以将Bootstrap徽章设置为药丸处于活动状态。
您可以尝试运行以下代码来实现此目的-
<!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> <h4>Active State in navigations</h4> <ul class = "nav nav-pills nav-stacked" style = "max-width: 260px;"> <li class = "active"> <a href = "#"> <span class = "badge pull-right">29</span> Home </a> </li> <li><a href = "#">Profile</a></li> <li> <a href = "#"> <span class = "badge pull-right">9</span> Messages </a> </li> </ul> </body> </html>
