scaleZ()
CSS
function
defines a transformation that resizes an element along the z-axis. Its result is a
<transform-function>
data type.

This scaling transformation modifies the z-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 not conserved.
scaleZ(-1)
defines an
axial symmetry
, with the z-axis passing through the origin (as specified by the
transform-origin
property).
In the above interactive examples,
perspective: 550px;
(to create a 3D space) and
transform-style: preserve-3d;
(so the children, the 6 sides of the cube, are also positioned in the 3D space), have been set on the cube.
注意：
scaleZ(sz)
is equivalent to to
scale3d
(1, 1, sz)
.
scaleZ(s)
s
<number>
representing the scaling factor to apply on the z-coordinate of each point of the element.
