必须加这个属性：transform-style: preserve-3d;

perspective: 900px; 设置了景深才能感到近大远小的感觉

            transform-style: preserve-3d;
            /* 
            必加transform-style: preserve-3d; 
            默认是flat:2d;
            */
            position: relative;
            margin: 0 auto;
            /* transform: rotateY(30deg);*/
             
            perspective: 900px;
            /* 设置景深 */
        }
        .center{
            position:absolute;
            width: 200px;
            height: 200px;
            background: red;
            left: 50%;
            top: 50%;
            margin-left: -100px;
            margin-top: -100px;
            transition: all 3s;
        }
        .box:hover .center{
            /* transform: translateZ(800px); */
            transform: translate3d(0,0,200px);
            /* 正值朝前，负值朝后 */
        }

    <div class="box">

transform: translateZ(80px); 等于transform: translate3d(0,0,80px);，里面的参数对应x,y,z轴
