The scaleX()
CSS function defines a transformation that resizes an element along the x-axis (horizontally). Its result is a <transform-function>
data type.
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 generally not conserved, except for multiples of 90 degrees. 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)
.
scaleX(s)
s
Is a <number>
representing the scaling factor to apply on the abscissa of each point of the element.
