scaleX
ScaleX refers to a CSS transform function that scales an element along the horizontal x-axis while leaving the y-axis unchanged. It is used inside the CSS transform property, typically in combination with other transforms like translateX, rotate, or scaleY.

A negative value like scaleX(-1) flips the element horizontally about the element's transform-origin, which by default is the element's center. The effect is applied after layout and is hardware accelerated in most browsers, making it suitable for smooth animations and interactive effects.
The default transform-origin is 50% 50% 0, but can be changed with transform-origin to control the pivot
