在Bootstrap中添加面板标题，以使用.panel-title类向面板添加标题。
您可以尝试运行以下代码来实现.panel-title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 = "panel panel-default"> <div class = "panel-heading"> <h3 class = "panel-title"> Panel with title </h3> </div> <div class = "panel-body"> Panel content </div> </div> </body> </html>
