scale3d()

{{CSSRef}} 

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

{{InteractiveExample("CSS Demo: scale3d()")}} 

transform: scale3d(1, 1, 1);

transform: scale3d(1.3, 1.3, 1.3);

transform: scale3d(0.5, 1, 1.7);

transform: scale3d(-1.4, 0.4, 0.7);

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 {{glossary("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 {{cssxref("<number>")}}  representing the abscissa (horizontal, x-component) of the scaling vector.
• sy
  • : Is a {{cssxref("<number>")}}  representing the ordinate (vertical, y-component) of the scaling vector.
• sz
  • : Is a {{cssxref("<number>")}}  representing the z-component of the scaling vector.
