scaleZ()

The scaleZ() CSS function modifies the z-coordinate of each element point by a constant factor, except if this 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(sz) is a shorthand for scale3d(1, 1, sz).

scaleZ(-1) defines an axial symmetry along the z-axis passing by the origin (as specified by the transform-origin property).

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 transform applies to the 3D space and cannot be represented on the plane.		$\left(\begin{array}{cc}10& 0\\ 01& 0\\ 0& 0& s\end{array}\right)$	$\left(\begin{array}{ccc}10& 0& 0\\ 01& 0& 0\\ 0& 0& s& 0\\ 0& 0& 0& 1\end{array}\right)$

Examples

HTML

<p>foo</p>
<p class="translated">bar</p>
<p class="scaled">bar</p>

CSS

p { 
  width: 50px;
  height: 50px;
  background-color: teal;
}

.translated{
  /* Adding a perspective to create a 3d space */
  transform: perspective(500px) translateZ(100px);
}

.scaled{
  /* Adding a perspective to create a 3d space */
  transform: perspective(500px) scaleZ(2) translateZ(100px);
}
