具体代码如下：

html部分代码：

    <head>      <title>旋转木马轮播图   rel="stylesheet" href="css/myStyle.css" rel="external nofollow" />   <script type="text/javascript" src="js/animate.js">

在html部分引入的myStyle.css文件部分代码

@charset "UTF-8";     blockquote,body,button,dd,dl,dt,fieldset,form,h1,h2,h3,h4, h5, h6, hr, input, legend, li, ol, p, pre, td, textarea, th, ul{   margin:0;   padding:0  }     body,button,input,select,textarea{   font:12px/1.5 "Microsoft YaHei", "微软雅黑", SimSun, "宋体", sans-serif;   color:#666;  }     ol,ul{   list-style:none  }     a{   text-decoration:none  }     fieldset,img{   border:0;   vertical-align:top;  }     a,input,button,select,textarea{   outline:none  }     a,button{   cursor:pointer  }     .wrap{   width:1200px;   margin:100px auto;  }  .slide{   height:500px;   position: relative;  }     .slide li{   position:absolute;   left:200px;   top:0  }     .slide li img{   width:100%  }     .arrow{   opacity:0;  }     .prev ,.next{   width:76px;   height:112px;   position:absolute;   top:50%;   margin-top:-56px;   background:url(../images/prev.png) no-repeat;   z-index:99;  }        .next{   right:0;   background-image:url(../images/next.png);  }

在html部分引入的myStyle.css文件部分代码

/**   * Created by RENPINGSHENG on 2018/4/6.   */     function animate(obj,json,fn) {   clearInterval(obj.timer);   obj.timer = setInterval(function () {    var flag = true;    for(var k in json){     if( k == "opacity"){      var leader = getStyle(obj,k) * 100;      var target = json[k] * 100;      var step = (target - leader) /10;      step = step > 0 ?

在html部分引入的my.js文件部分代码

/**   * Created by RENPINGSHENG on 2018/4/6.   */        window.onload = function () {   var wrap = document.getElementById("wrap");   var slide = document.getElementById("slide");   var ul = slide.children[0];   var lis = ul.children;   var arrow = document.getElementById("arrow");   var arrRight = document.getElementById("arrRight");   var arrLeft = document.getElementById("arrLeft");      var config = [    {     width:400,     top:20,     left:50,     opacity:0.2,     zIndex:2    },    {     width:600,     top:70,     left:0,     opacity:0.8,     zIndex:3    },    {     width:800,     top:100,     left:200,     opacity:1,     zIndex:4    },    {     width:600,     top:70,     left:600,     opacity:0.8,     zIndex:3    },    {     width:400,     top:20,     left:750,     opacity:0.2,     zIndex:2    }   ];      wrap.onmouseover = function () {    animate(arrow,{"opacity":1});   }   wrap.onmouseout = function () {    animate(arrow,{"opacity":0});   }   function assign() {    for(var i = 0;i < lis.length;i++){     animate(lis[i],config[i],function(){      flag = true;     })    }   }      var flag = true;   assign();   arrRight.onclick = function () {    flag = false;    config.push(config.shift());    assign();   };   arrLeft.onclick = function () {    flag = false;    config.unshift(config.pop());    assign();   }  }
