用html+CSS制作一个3D旋转相册
前端html+css知识小应用
首先，我们要新建一个总的文件夹，文件夹里面新建一个images的文件夹，用来装图片，一个HTML文件，这里要注意，images文件夹和html文件是并列属性的，编辑器我用的webstrom，如下图所示：
然后，在images里面保存10张图片加1张背景图片（背景图片可以不设置），图片名字按顺序用1.jpg到10.jpg，背景图片这里用的star.jpg。如下图所示：
接下来就是代码部分了，新建一个html文件，名字随意，代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>致青春</title>
<style>
*{margin: 0;padding: 0;}
html,body{height: 100%;}
body{
display: flex;
perspective: 1000px;
transform-style: preserve-3d;
background-image: url(images/star.jpg);
height:100%;
width: 100%;
}
#box{
position: relative;
display: flex;
width: 130px;
height: 200px;
margin: auto;
transform-style: preserve-3d;
transform: rotateX(-10deg);
}
#box > div{
transform-style: preserve-3d;
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
line-height: 200px;
font-size: 50px;
text-align: center;
box-shadow:0 0 10px #fff;
-webkit-box-reflect:below 10px -webkit-linear-gradient(top,rgba(0,0,0,0) 40%,rgba(0,0,0,.8) 100%);
}
/* #box > div:nth-child(1){
background: skyblue;
transform: translate3d(0,0,300px) rotateY(45deg);
}
#box > div:nth-child(2){
background: pink;
transform: rotateY(0deg);
}
#box > div:nth-child(3){
background: purple;
transform: translate3d(0,0,300px) rotateY(-45deg);
}
*/
#box p{
position: absolute;
left: 0;
top: 0;
bottom: 0;
right: 0;
margin: auto;
width: 1200px;
height: 1200px;
background: -webkit-radial-gradient(center center,600px 600px,rgba(50,50,50,1),rgba(0,0,0,0));
border-radius: 50%;
transform: rotateX(90deg) translate3d(-600px,0,-105px);
}
</style>
</head>
<body>
<div id="box">
<div></div>
<div></div>
<div></div>

<script>
setTimeout(init,100);
function init(){
var obox = document.getElementById('box'),
aDiv = obox.getElementsByTagName('div');
for (var i = 0; i < aDiv.length; i++) {
aDiv[i].style.background = "url(images/"+(i+1)+".jpg) center/cover";
aDiv[i].style.transform = "rotateY("+(i*36)+"deg) translate3d(0,0,350px)";
aDiv[i].style.transition = "transform 1s "+(aDiv.length-i)*0.2+"s";
}
var sX,
sY,
nX,
nY,
desX = 0,
desY = 0,

}
this.onmouseup = function(){

obox.timer = setInterval(function(){

obox.style.transform = "rotateX("+(-tY)+"deg) rotateY("+tX+"deg)";
if (Math.abs(desX)<0.5 && Math.abs(desY)<0.5) {
clearInterval(obox.timer);
}
},13);
}
return false;
}
//滚轮放大缩小
mousewheel(document,function(e){
e = e || window.event;
var d = e.wheelDelta/120 || -e.detail/3;
if (d>0) {
index-=20;
}else{
index+=30;
}
(index<(-1050)&&(index=(-1050)));
document.body.style.perspective = 1000 + index + "px";
})
function mousewheel(obj,fn){
document.onmousewheel===null?obj.onmousewheel=fn:addEvent(obj,"DOMMouseScroll",fn)
}
function addEvent(obj,eName,fn){
obj.attachEvent?obj.attachEvent("on"+eName,fn):obj.addEventListener(eName,fn);
}
}

最后保存一下再运行就可以看到效果图了，因为本人是鞠婧祎的音乐粉丝，所以用的是鞠婧祎的图片，背景图片是在网上搜的星空图片，下面是我的效果图：
这个小demo保存之后，以后打开只要点击那个html文件，都可以看到这个效果。鼠标放在图片上，按住然后往上下左右滑都会旋转的
