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 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; }
