怎么没人回呀
如果你想使一个没有内容的a标签上display:block;
尝试 在.left,.right 添加一个空背景图片,如:background-image:url(about:blank);
或者你可以在a里添加文字
left
right
然后用 .left,.right{text-indent:-3000px;}文字位置偏移3000个像素,超过屏幕显示范围而不被显示。
<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(http://d.lanrentuku.com/down/js/xiangce-848/images/42813100.jpg) no-repeat center center;}.right{right:0; }a.right:hover{background:url(http://d.lanrentuku.com/down/js/xiangce-848/images/42813100.jpg) no-repeat center center;}</style>
