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.

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.

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

Examples
