Bootstrap导航栏形式类的用法
要在CSS中创建导航栏，请使用navbar-form类
示例
<!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: #F5CBA7;"> <nav class = "navbar navbar-default" role = "navigation"> <div class = "navbar-header"> <a class = "navbar-brand" href = "#">My Website</a> </div> <div> <form class = "navbar-form navbar-left" role = "search"> <div class = "form-group"> <input type = "text" class = "form-control" placeholder = "Search"> </div> <button type = "submit" class = "btn btn-default">Submit</button> </form> </div> </nav> </body></html>
