代码演示效果：
1.运用jQuery，动画样式进行轮播图切换
2.前提，需要引入animate.css（官网下载就有）
HTML代码：
<head>
<meta charset="UTF-8">
<title>手风琴</title>
<link rel="stylesheet" href="../animate.css">
<link rel="stylesheet" href="css/index.css">
<script src="../jquery-3.1.0.js"></script>
<!-- <script src="js/手风琴index.js"></script>-->
</head>
<body>
<div class="bg"></div>
<div class="bg"></div>
<div class="bg"></div>
<div class="bg bg-active"></div>
<div class="main">
<ul>
<li><div><p>穿越火线</p></div></li>
<li><div><p>王者荣耀</p></div></li>
<li><div><p>使命召唤</p></div></li>
<li class="li-active"><div><p>英雄联盟</p></div></li>
</ul>
</div>
</body>
script代码：
<script>
$(function () {
$("li").mouseenter(function () {
//stop()阻止动画效果
$(this).stop().animate({width:"700px"},1000,"linear").fadeIn();
$(this).siblings("li").stop().animate({width:"100px"},1000,"linear").fadeIn();
$(".bg").eq($(this).index()).siblings(".bg").stop().fadeOut();
$(".bg").eq($(this).index()).stop().animate({top:"700px"},400,"linear").fadeIn();
});
});
</script>
css代码：
*{
margin: 0;
padding: 0;
}
html,body, .bg{
height: 700px;
width: 1400px;
overflow: hidden;
}
