css代码：

        <style>*{    margin:0px;    padding:0px;}html{    height:100%;}body{    width:100%;    height:100%;    background:url("images/wallpaper4.jpg");    background-size:100% 100%;    overflow: hidden;}.wrap{    position:relative;    width:1156px;    height:450px;    margin:50px auto;}.wrap ul li{    position:relative;    z-index:10;    width:230px;    height:150px;    float:left;    list-style:none;    border-right:1px dotted #ccc;    border-bottom:1px dotted #ccc;    background:url("images/clients.png") no-repeat;    -webkit-transition:1s;    -moz-transition:1s;    -ms-transition:1s;    -o-transition:1s;    transition:1s;}.box{    position:absolute;    left:0px;    top:0px;    z-index:2;    width:230px;    height:150px;    background:rgba(0,0,0,.2);    -webkit-transition:1s;    -moz-transition:1s;    -ms-transition:1s;    -o-transition:1s;    transition:1s;}        </style>

javascript代码：

    <script>var oLi = document.getElementsByTagName("li");var box = document.getElementsByClassName("box")[0];for (var i = 0;i<oLi.length ;i++ ){    oLi[i].onmousemove = function(){        var _left = this.offsetLeft;        var _top = this.offsetTop;        box.style.left = _left + "px";        box.style.top = _top + "px";        this.style.backgroundPositionY = "-150px";    }    oLi[i].onmouseout = function(){        this.style.backgroundPositionY = "0px";    }}        </script>
