一、案列效果

二、案列思路

1、先将平面上的6个DIV拼接在一起。形成一张类似于3d立方体图形展开的平面图。

2、我们需要将每一个面旋转到相应的位置上，每一个面的旋转轴都是不一样的。上下，左右，分别对应的旋转轴,以及旋转角度分别是：bottom(90deg),top(-90deg),right(90deg),left(-90deg)。同时要注意在旋转后面的时候，旋转轴为Z轴，并不是上下，左右边。浏览器上面的坐标系是这样的：Z轴是屏幕里外两个方向（向外为正，向里为负），X轴的水平方向（向右为正，向左为负）；

3、接下来还有一个关键的步骤，就是当变换导致元素在 3D 空间中旋转时，指定当元素背面朝向观察者时不可见；

4、接下来我们要做的就是设置一下所处环境，我们要设置成3D的环境，具体的语法形式如下：transform-style: preserve-3d;

5、然后我们为了让立方体旋转起来，以便更好的实现3D效果。首先找到旋转中心，在3D魔方中，旋转中心就是立方体的几何中心。

三、案列目录
