The scale3d()
CSS function defines a transformation that resizes an element in 3D space. Because the amount of scaling is defined by a vector, it can resize different dimensions at different scales. Its result is a <transform-function>
data type.

This scaling transformation is characterized by a three-dimensional vector. Its coordinates define how much scaling is done in each direction. If all three coordinates are equal, the scaling is uniform (isotropic) and the aspect ratio of the element is preserved (this is a homothetic transformation).
When a coordinate value is outside the [-1, 1] range, the element grows along that dimension; when inside, it shrinks. If it is negative, the result a point reflection in that dimension. A value of 1 has no effect.
Syntax
The scale3d()
function is specified with three values, which represent the amount of scaling to be applied in each direction.
scale3d(sx, sy, sz)
Values
sx
- Is a
<number>
representing the abscissa of the scaling vector. sy
- Is a
<number>
representing the ordinate of the scaling vector. sz
- Is a
<number>
representing the z-component of the scaling vector.

This transformation applies to the 3D space and can't be represented on the plane. |
Examples
Without changing the origin
HTML
<div>Normal</div> <div class="scaled">Scaled</div>
CSS
div { width: 80px; height: 80px; background-color: skyblue; } .scaled { transform: perspective(500px) scale3d(2, 0.7, 0.2) translateZ(100px); background-color: pink; }
Result
Translating the origin of the transformation
HTML
<div>Normal</div> <div class="scaled">Scaled</div>
CSS
div { width: 80px; height: 80px; background-color: skyblue; } .scaled { transform: perspective(500px) scale3d(2, 0.7, 0.2) translateZ(100px); transform-origin: left; background-color: pink; }
