+
+语法
+
+```css

+transform: translateY(y);
+transform: translateZ(z);
+```
+

+## 1、透视
+
+perspective 视线透视效果
+
+透视效果：近大远小，近实远虚
+
+父级添加属性
+
+```css
+/* 透视距离(视距): 人眼睛到屏幕的距离 */
+perspective: 像素值; /* (800-1200) */
+```
+
+示例：

+## 2、空间旋转 rotate
+
+语法
+
+```css
+transform: rotateZ(角度);
+transform: rotateX(角度);
+transform: rotateY(角度);
+```
+
+示例：
+
+[](demo/transform-rotate3d.html ':include :type=code')
+
+[](demo/transform-rotate3d.html ':include height=220')
+
+## 左手法则: 判断旋转方向
+
+左手握住旋转轴，拇指指向正值方向，手指弯曲方向为旋转正值方向
+
+## rotate3d（了解）
+
+自定义旋转周的位置及旋转角度
+
+```css
+rotate3d(x, y, z, 角度);
+```
+
+x, y, z 取 0-1 之间的数字
