1. 立方体的上下:
.cubeBottom{ transform: rotateX(90deg) ; transform-origin:center bottom ; /* :绕x旋转,主要确定y的高度 : right bottom , 1px 300px, 2px 300px,.. 100px 300px .. */ }
2. 立方体的左右:
.cubeLeft{ transform: rotateY(90deg) ; transform-origin:left center ; /* :绕Y旋转,主要确定x : left bottom , left 300px, 0 300px,..0 500px .. */ }
3. 立方体的前后:
.cubeFront{ transform:translateZ(0px); } .cubeBack{ transform:translateZ(-300px); }
4 立方体实现:注意
/* 透视中心和透视距离*/
perspective-origin: 0 1000px ;
perspective: 2000px;
/* 效果: 平面还是3d立体 */
transform-style: preserve-3d;
