matrix()

A função CSS matrix() define uma matriz de transformação 2D homogênea. Isso resulta em um dado do tipo <transform-function> .

Nota: 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.

Nota: Until Firefox 16, Gecko accepted a <length> (en-US) 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.

[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;
}
