它就用到了一个比较简单的坐标y 轴旋转那咱们看一下他的代码

html的代码:
  <div class="kj" id="kj">
    <div class="mian"><img src="img/p1.jpg" alt=""></div>
    <div class="mian"><img src="img/p2.jpg" alt=""></div>
    <div class="mian"><img src="img/p3.jpg" alt=""></div>
    <div class="mian"><img src="img/p4.jpg" alt=""></div>
    <div class="mian"><img src="img/p5.jpg" alt=""></div>
    <div class="mian"><img src="img/p6.jpg" alt=""></div>
    <div class="mian"><img src="img/p7.jpg" alt=""></div>
    <div class="mian"><img src="img/p8.jpg" alt=""></div>
    <div class="mian"><img src="img/p9.jpg" alt=""></div>
  </div>

首先要建九个盒子放九张图片,这个很容易理解的。

css的代码



          body{
            background: #6daf39;(背景加了个颜色 主要是好看)
          }
          .xj{
          perspective:600px;(这是井深)
          }
          .kj{
          transition: 1s;(运动时间)
          transform-style:preserve-3d;(实现3d效果 当然这是非常重的)
          width:200px;
          height: 300px;
          margin:80px auto;
          position: relative;
          transform: rotateY(0deg) rotateX(0deg) translateZ(-275px);
          transform-origin: center center -275px;
          }

      .mian{
        position:absolute;
        font-size: 50px;
        color:#fff;
        text-align: center;
        line-height: 300px;
      }
      .mian:nth-child(1){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(0deg)translateZ(275px);
      }
      .mian:nth-child(2){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(40deg)translateZ(275px);
      }
      .mian:nth-child(3){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(80deg)translateZ(275px);
      }
      .mian:nth-child(4){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(120deg)translateZ(275px);
      }
      .mian:nth-child(5){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(160deg)translateZ(275px);
      }
      .mian:nth-child(6){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(200deg)translateZ(275px);
      }
      .mian:nth-child(7){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(240deg)translateZ(275px);
      }
      .mian:nth-child(8){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(280deg)translateZ(275px);
      }
      .mian:nth-child(9){
        width:200px;
        height: 300px;
        background: #ff2223;
        transform: rotateY(320deg)translateZ(275px);
      }

css就到这里,很简单的;

js的代码
    kj.onclick=function () {
      cishu++;
      var jiaodu=40*cishu;


      kj.style.transform="rotateY("+jiaodu+"deg)translateZ(-275px)"
    }

(kj)就是3d空间,点击kj要是一种效果,就要有一种方法或步骤;
3d空间样式rotateY(这就是上下轴旋转)translateZ(Z这就是3d立体字轴;让3d空间后移275px找到轴心位置)

完毕 希望大家看到这篇文章后能够学到知识。
