Common CSS styles

8. Transformation style

Change the size, transparency, rotation angle, distortion, etc. of the element.

　transform : none |

　 represents one or more transformation functions, separated by spaces, which means that we can perform multiple attribute operations of transform on an element at the same time.

Warm reminder: In the past, our overlay effects were separated by commas, but when using multiple attributes in transform, they were separated by spaces.

　1)translate()

　　Specify the 2D translation of the object. The first parameter corresponds to the X-axis, and the second parameter corresponds to the Y-axis. If the second parameter is not provided, the default value is 0. ​​

　Example source code:

　　3）过渡函数（transition-timing-function）

　　　　指过渡的“缓动函数”。主要用来指定浏览器的过渡速度，以及过渡期间的操作进展情况。

　　　　其中要包括以下几种函数：

　　　　①ease : 默认值，逐渐变慢(等于 cubic-bezier(0.25,0.1,0.25,1))

　　　　②linear : 匀速过渡效果(等于 cubic-bezier(0,0,1,1))

　　　　③ease-in : 加速的过渡效果(等于 cubic-bezier(0.42,0,1,1))

　　　　④ease-out : 减速的过渡效果(等于 cubic-bezier(0,0,0.58,1))

　　　　⑤ease-in-out : 加速然后减速(等于cubic-bezier (0.42, 0, 0.58, 1))

　　　　⑥cubic-bezier(n,n,n,n)：在 cubic-bezier 函数中定义自己的值，可能的值是 0 至 1 之间的数值。
