matrix()

The matrix() CSS function defines a homogeneous 2D transformation matrix. Its result is a <transform-function> data type.

Note: matrix(a, b, c, d, tx, ty) is a shorthand for matrix3d(a, b, 0, 0, c, d, 0, 0, 0, 0, 1, 0, tx, ty, 0, 1).

Syntax

The matrix() function is specified with six values. The constant values are implied and not passed as parameters; the other parameters are described in the column-major order.

Note: Until Firefox 16, Gecko accepted a <length> value for tx and ty.
matrix(a, b, c, d, tx, ty)

Values

a b c d
Are <number>s describing the linear transformation.
tx ty
Are <number>s describing the translation to apply.
Cartesian coordinates on ℝ2 Homogeneous coordinates on ℝℙ2 Cartesian coordinates on ℝ3 Homogeneous coordinates on ℝℙ3
a c b d a c tx b d ty 0 0 1 a c tx b d ty 0 0 1 a c 0 tx b d 0 ty 0 0 1 0 0 0 0 1
[a b c d tx ty]

The values represent the following functions:
matrix( scaleX(), skewY(), skewX(), scaleY(), translateX(), translateY() )

Examples

HTML

<div>Normal</div>
<div class="changed">Changed</div>

CSS

div {
  width: 80px;
  height: 80px;
  background-color: skyblue;
}

.changed {
  transform: matrix(1, 2, -1, 1, 80, 80);
  background-color: pink;
}
