3d 转换
tranform:rotateX(x) 沿X轴旋转
transform:rotateY(y) 沿y轴旋转
transform:rotateZ(z) 沿z轴旋转
transform:rotate3d(x,y,z,deg)
rotate3d 旋转角度根据比例计算：
x²+y²+z²=1
计算每个轴所占的比例*deg

计算：如rotate3d(1,2,1,90deg)
则 x²+(2x)²+x²=1
得 x=根号6/6
则 三个轴旋转的角度分别为 根号6/6*1 根号6/6*2 根号6/6*1
transform:translateX 水平，与2d一样
transform:translateY 竖直，与2d一样
transform:translateZ z轴方向，视觉上没有区别，常用于遮罩

perspective:none | 数值
perspective属性指定了观察者与z=0平面的距离，使具有三维位置变换的元素产生透视效果。z>0的三维元素比正常大，而z<0时则比正常小，大小程度由该属性的值决定
三维元素在观察者后面的部分不会绘制出来，即z轴坐标值大于perspective属性值的部分
属性值为0或负值或none（none是默认值）时，没有透视效果
perspective-origin 透视中心点
