scaleX()
The scaleX() CSS function defines a transformation that resizes an element along the x-axis (horizontally). Its result is a <transform-function> data type.
It modifies the abscissa of each element point by a constant factor, except when the scale factor is 1, in which case the function is the identity transform. The scaling is not isotropic, and the angles of the element are not conserved. scaleX(-1) defines an axial symmetry, with a vertical axis passing through the origin (as specified by the transform-origin property).
Note: scaleX(sx) is equivalent to scale(sx, 1) or scale3d(sx, 1, 1).
Syntax
scaleX(s) Values
s Is a <number> representing the scaling factor to apply on the abscissa of each point of the element.
