scaleY()
The scaleY()
CSS function defines a transformation that resizes an element along the
y-axis (vertically). Its result is a <transform-function>
data type.
Try it
It modifies the ordinate 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.
scaleY(-1)
defines an axial symmetry, with a horizontal axis passing through the origin (as specified by the transform-origin
property).
Note: scaleY(sy)
is equivalent to
scale(1, sy)
or
scale3d(1, sy, 1)
.
transform: rotateX(180deg);
=== transform: scaleY(-1);
