要将标签转变为药丸，请使用.nav-pills类，
<ul class = "nav nav-pills">
您可以尝试运行以下代码来实现Bootstrap药丸：
<!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> <h2>Subjects</h2> <ul class = "nav nav-pills"> <li class = "active"><a href = "#">Java</a></li> <li><a href = "#">WordPress</a></li> <li><a href = "#">JavaScript</a></li> <li><a href = "#">AngularJS</a></li> </ul> </body> </html>
