基于bootstrap.js制作简洁模态登录框，点击按钮弹出登录框表单，输入账号，密码效果。这是一款响应式的弹窗登录框插件。

1、head引入css文件

<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css" />

2、head引入js文件

<script type="text/javascript" src="js/jquery-1.12.4.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

3、body引入HTML代码

<div class="modal fade" id="myModal">
