请问怎么没有3d的翻页效果？只是点击后简单地变页数，各位指教一下
<style type="text/css">
#wrap{
-webkit-perspective:800px;
-webkit-perspective-origin:50% 50%;
overflow:hidden
}
#pageground{
width:400px;
height:400px;
margin:0 auto;
-webkit-transform-style:-webkit-preserve-3d;
position:relative;
}
.page{
width:360px;
height:360px;
padding:20px;
background-color:#FF0000;
color:#FFFFFF;
font-weight:bold;
font-size:360px;
line-height:360px;
text-align:center;
position:absolute;
}
#page1{
-webkit-transform-origin:bottom;
-webkit-transition:-webkit-transform 1s linear;
}
#page2,#page3,#page4,#page5,#page6{
-webkit-transform-origin:bottom;
-webkit-transition:-webkit-transform is linear;
-webkit-transform:rotateX(90deg);
}
#op{
text-align:center;
margin:40px auto;
}
</style>
<script type="text/javascript">
var curindex=1
function next(){
if(curindex==6)
return;
else
var curpage=document.getElementById("page"+curindex);
curpage.style.webkitTransform="rotateX(-90deg)";
curindex ++;
var nextpage=document.getElementById("page"+curindex);
nextpage.style.webkitTransform="rotateX(0deg)";
}
function pre(){
}
</script>
</head>
