今天工作中要用到一个轮播功能，在网上找了一些，觉得有些过于繁琐，于是自己动手写了一个，效果如图：
代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>轮播图</title>

<style>
.oop_inner{
margin:0 auto;
position:relative;
top:10px;
width:640px;
height:424px;
box-shadow:1px 2px 3px #666;
overflow:hidden;
}
.oop_banner{
position:absolute;
width:2600px;
/* left:-640px; */
}
.oop_banner img{
float:left;
width:640px;
}
.oop_li{
position:absolute;
left:45%;
bottom:20px;
}
.oop_li span{
display:block;
float:left;
margin-right: 10px;
width:15px;
height:7px;
background:#fff;
box-shadow: 1px 1px;
cursor:pointer;
}
.oop_li span:hover{
background:#000;
}
.oop_li .on{
