使用输入组，您可以轻松地在基于文本的输入中添加和添加文本或按钮。Bootstrap中输入组类的用法相同。
您可以尝试运行以下代码以实现输入组类-
<!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 style = "padding: 100px 100px 10px;"> <form class = "bs-example bs-example-form" role = "form"> <div class = "input-group"> <span class = "input-group-addon">@</span> <input type = "text" class = "form-control" placeholder = "twitterhandle"> </div> <br> <div class = "input-group"> <input type = "text" class = "form-control"> <span class = "input-group-addon">.00</span> </div> <br> <div class = "input-group"> <span class = "input-group-addon">$</span> <input type = "text" class =" form-control"> <span class = "input-group-addon">.00</span> </div> </form> </div> </body> </html>
