一个完全响应的jQuery和CSS3驱动的翻转时钟插件，以自定义日期时间格式显示数字倒计时计时器。

参见：

• JavaScript中的7个最佳翻转时钟式倒计时插件

如何使用它:

1.为翻转倒计时时钟构建HTML。

• 数据日期时间：日期时间
• 数据模板：自定义格式
• 数据标签：自定义标签
• 数据反向：true=倒计时模式

<div class="flipper" 
     data-datetime="2020-01-01 00:00:00" 
     data-template="ddd|HH|ii|ss" 
     data-labels="Days|Hours|Minutes|Seconds" 
     data-reverse="true"
     id="myFlipper">
</div>

2.包含JavaScript文件jquery.flipper-aresponsive.js查询加载jQuery库之后。

<script src="/path/to/jquery.slim.min.js"></script>
<script src="/path/to/jquery.flipper-responsive.js"></script>

3.初始化翻转倒计时时钟。

$(function(){
  $('#myFlipper').flipper('init');
});

4.所需的CSS/CS3样式。
