首先，来看下，是什么效果吧，上效果图 ↓

其实这个东西，很容易制作，先说下思路， 把照片都给叠在一起，然后 rotateY 旋转，给每张图片 旋转不一样的角度能构成一圈， 然后translateZ 出去就好了，最后一步，父级转起来。
搭建好基本的 html 和 css ↓ 已经写好注释啦。

基本架子搭建好后，给每张图片，旋转不同的位置。

旋转好位置后，添加 translateZ() 参数，分开图片。因为，translateZ 也是 transform 的参数之一，所以要添加在rotate后面接上。最后，记得在15行添加上 perspective 属性。不懂什么是 perspective 属性的话，请点击→ css3系列之详解perspective

然后，我们给父级 加上旋转的功能就OK了。
