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.

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;
}
