scaleZ() CSS function

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

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

Try it

transform: scaleZ(1);
transform: scaleZ(1.4);
transform: scaleZ(0.5);
transform: scaleZ(-1.4);
<section class="default-example" id="default-example">
  <div class="transition-all" id="example-element">
    <div class="face front">1</div>
    <div class="face back">2</div>
    <div class="face right">3</div>
    <div class="face left">4</div>
    <div class="face top">5</div>
    <div class="face bottom">6</div>
  </div>
</section>
#default-example {
  background: linear-gradient(skyblue, khaki);
  perspective: 800px;
  perspective-origin: 150% 150%;
}

#example-element {
  width: 100px;
  height: 100px;
  perspective: 550px;
  transform-style: preserve-3d;
}

.face {
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100%;
  height: 100%;
  position: absolute;
  backface-visibility: inherit;
  font-size: 60px;
  color: white;
}

.front {
  background: rgb(90 90 90 / 0.7);
  transform: translateZ(50px);
}

.back {
  background: rgb(0 210 0 / 0.7);
  transform: rotateY(180deg) translateZ(50px);
}

.right {
  background: rgb(210 0 0 / 0.7);
  transform: rotateY(90deg) translateZ(50px);
}

.left {
  background: rgb(0 0 210 / 0.7);
  transform: rotateY(-90deg) translateZ(50px);
}

.top {
  background: rgb(210 210 0 / 0.7);
  transform: rotateX(90deg) translateZ(50px);
}

.bottom {
  background: rgb(210 0 210 / 0.7);
  transform: rotateX(-90deg) translateZ(50px);
}

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 scale3d(1, 1, sz).

Syntax

css
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 ℝ^2 Homogeneous coordinates on ℝℙ^2 Cartesian coordinates on ℝ^3 Homogeneous coordinates on ℝℙ^3
This transformation applies to the 3D space and can't be represented on the plane.

(1000010000s00001)\left( \begin{array}{cccc} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & s & 0 \\ 0 & 0 & 0 & 1 \end{array} \right)

Formal syntax

<scaleZ()> = 
scaleZ( [ <number> | <percentage> ] )
