transform
在CSS3中transform主要包括以下几种：旋转rotate、扭曲skew、缩放scale和移动translate以及矩阵变形matrix。下面我们一起来看看CSS3中transform的旋转rotate、扭曲skew、缩放scale和移动translate
1.rotate、scale、translate、skew
- 旋转 依次为 z轴、z轴 、x轴 、y轴
rotate(30deg) rotateZ(30deg) rotateX(30deg) rotateY(30deg) - 缩放 依次为 x方向y方向、x方向、y方向
scale: scale(1.2,0.8) scaleX(1.2) scaleY(0.8) - 位移 依次为 x方向y方向、x方向、y方向
translate(20px,-30px) translateX(20px) translateY(-30px)
-扭曲 依次为 x轴y轴、x轴、y轴
skew(anglex,angley) skewX(angle) skewY(angle)

2.transform-origin
- transform-origin 属性用来设置 transform 变换的基点位置。默认情况下，基点位置为元素的中心点。
语法：
`
transform-origin: x-axis y-axis z-axis
`
| 名称 | 值 | 描述 |
|---|---|---|
| x-axis | 位置（left、center、right）/ 百分数 / 数值 | x轴 |
| y-axis | 位置（top、center、bottom）/ 百分数 / 数值 | y轴基点坐标 |
| z-axis | 数值 | z轴基点坐标 |
