Question: Move the mouse to the a tag and add an arrow image to the a tag. It is normal under Google, but there is no response under IE. How should I modify it?
The correct modified code is as follows:
CCS code:

<style type="text/css">
.box{ width:500px; height:300px; border:5px solid #00F;position:relative;}
.left,.right{display:block;top:0;width:50px; height:300px;position:absolute; z-index:99; background:url(一张透明图片.png) repeat;}
.left span,.right span,.img{position:relative;}
.img{ z-index:10;}
.left{left:0;}
a.left:hover{background:url(/uploads/201411/f94feeae3b52fd2bb9051d9e0bb70da21.jpg) no-repeat center center;}
.right{right:0; }
a.right:hover{background:url(/uploads/201411/f94feeae3b52fd2bb9051d9e0bb70da21.jpg) no-repeat center center;}
