纯CSS做一个3D正方体的小例子

<style>
.wrap {
width: 500px;
height: 500px;
perspective: 800px;
/* 旋转原点 */perspective-origin: 50%100px;
margin-top: 300px;
margin-left: 300px;
    }
.cube {
position: relative;
width: 200px;
height: 200px;
/* 确保6个面都处于3D立体状态 */transform-style: preserve-3d;
animation: spin6slinearinfinite;
/*设置动画*/    }
.cubediv {
position: absolute;
width: 200px;
height: 200px;
text-align: center;
line-height: 200px;
color: rgba(0, 0, 0, 0.5);

background: rgba(255, 255, 255, 0.1);

    }
/* 上下左右 */@keyframesspin {

        }
