(3) scale(x,y): The element is scaled in the horizontal and vertical directions at the same time (the X-axis and Y-axis are scaled at the same time) ;
1, scaleX(x)
Syntax:
transform:scaleX(x)

x means that the element is along the horizontal direction ( X-axis) The zoom factor. If it is greater than 1, it means zooming in; if it is less than 1, it means zooming out.
It will be easy to understand if you think about the concept of multiples.

Syntax:
transform:scaleY(y)
Description:
y means that the element is along the vertical direction (Y Axis) The zoom factor. If it is greater than 1, it means zooming in; if it is less than 1, it means zooming out.

Description:
x means that the element is along the horizontal direction (X-axis) scaling factor, y represents the scaling factor of the element along the vertical direction (Y-axis).
Note that Y is an optional parameter. If the Y value is not set, it means that the scaling factors in the X and Y directions are the same (magnifying the same factor at the same time).
