scaleX()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.
The scaleX()
CSS function defines a transformation that resizes an element along the
x-axis (horizontally). Its result is a <transform-function>
data type.
Try it
It modifies the abscissa (horizontal, x-coordinate) 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)
.
Syntax
scaleX(s)
Values
s
-
Is a
<number>
representing the scaling factor to apply on the abscissa (horizontal, x-coordinate) of each point of the element.
