对于每个.nav类，如果添加.disabled类，它将创建一个灰色链接，该链接也会禁用：hover状态。
您可以尝试运行以下代码来设置禁用的链接-
<!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 style = "background: #FADBD8;"> <h2>Website</h2> <ul class = "nav nav-tabs nav-justified"> <li class = "active"><a href = "#">Home</a></li> <li><a href = "#">Team</a></li> <li><a href = "#">Authors</a></li> <li><a href = "#">MVPs</a></li> </ul> <h2>Website (With disabled links)</h2> <ul class = "nav nav-tabs nav-justified"> <li class = "active"><a href = "#">Home</a></li> <li><a href = "#">Team</a></li> <li class = "disabled"><a href = "#">Authors (disabled link)</a></li> <li><a href = "#">MVPs</a></li> </ul> </body> </html>
