The 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.
Note: scaleZ(sz)
is equivalent to to scale3d(1, 1, sz)
.
Syntax
scaleZ(s)
Values
s
- Is a
<number>
representing the scaling factor to apply on the z-coordinate of each point of the element.
Cartesian coordinates on ℝ2 | Homogeneous coordinates on ℝℙ2 | Cartesian coordinates on ℝ3 | Homogeneous coordinates on ℝℙ3 |
---|---|---|---|
This transformation applies to the 3D space and can't be represented on the plane. |
Examples
HTML
<div>Normal</div> <div class="perspective">Translated</div> <div class="scaled-translated">Scaled</div>
CSS
div { width: 80px; height: 80px; background-color: skyblue; } .perspective { /* Includes a perspective to create a 3D space */ transform: perspective(400px) translateZ(-100px); background-color: limegreen; } .scaled-translated { /* Includes a perspective to create a 3D space */ transform: perspective(400px) scaleZ(2) translateZ(-100px); background-color: pink; }
