倒计时

需要先引入相关的CSS和JS文件：

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

<script src="static/js/aui.min.js" type="text/javascript" charset="utf-8"></script>

<script src="static/js/aui.getdate.js" type="text/javascript" charset="utf-8"></script>

<script src="lib/jquery/jquery-2.1.3.min.js" type="text/javascript" charset="utf-8"></script>

示例代码

<style>
    body{background: #FFF;}
    .content{width: 100%; padding: 15px; box-sizing: border-box; text-align: center;}
    .countdown-warp{width: auto; text-align: center; font-size: 14px; padding: 30px 0; display: inline-block; margin: 0 auto;}
