matrix()

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 matrix() CSS function defines a homogeneous 2D transformation matrix. Its result is a data type.

Try it

transform: matrix(1.2, 0.2, -1, 0.9, 0, 20);

transform: matrix(0.4, 0, 0.5, 1.2, 60, 10);

transform: matrix(0, 1, 1, 0, 0, 0);

transform: matrix(0.1, 1, -0.3, 1, 0, 0);

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.

css

matrix(a, b, c, d, tx, ty)

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

Values

a b c d: Are s describing the linear transformation.
tx ty: Are s describing the translation to apply.

$\begin{pmatrix} a & c \\ b & d \end{pmatrix}$	$\left( \begin{array}{ccc} a & c & tx \\ b & d & ty \\ 0 & 0 & 1 \\ \end{array} \right)$	$\left( \begin{array}{ccc} a & c & tx \\ b & d & ty \\ 0 & 0 & 1 \\ \end{array} \right)$	$\left( \begin{array}{cccc} a & c & 0 & tx \\ b & d & 0 & ty \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \\ \end{array} \right)$
$\begin{pmatrix} a & c \\ b & d \end{pmatrix}$	`[a b c d tx ty]`

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

Formal syntax

 = 
  matrix( #{6} )
