The <transform-function> CSS data type denotes a function to apply to an element's representation in order to modify it. Usually such transform may be expressed by matrices and the resulting images can be determined using matrix multiplication on each point.
Coordinates for 2D graphics
There are several coordinates model used when describing transformation. The most usual are the Cartesian coordinates and the homogenous coordinates.
Cartesian coordinates
In Cartesian coordinates each point of the Euclidian space is described using two values, the abscissa and the ordinate. The origin, the (0, 0) is the top-left corner of the element. Unlike the usual geometric convention, and like most cases in computer graphics, the y-axis goes to the bottom. Each point is mathematically described using the vector notation (x,y).
Each linear function is described using a 2x2 matrix like:
$\left(\begin{array}{cc}a& c\\ b& d\end{array}\right)$
Applying the transformation consists in doing, for each point, the matrix multiplication between both:
It is possible to apply several transformations in a row:
With this notation, it is possible to describe, and therefore composite, most usual transformations: rotations, scaling or skewing. In fact all transformations that are linear functions can be described. One major transformation is not linear and therefore must be special-cased when using this notation: translation. The translation vector (tx, ty) must be expressed separately, as two more parameters.
Mobius homogenous coordinates in projective geometry
leading to 3x3 transformation matrices, though more complex and unusual for non-specialist, doesn't suffer from the translation limitation as these can be expressed as linear functions in this algebra, removing the need for special cases

Functions defining transformations
matrix()
The matrix() CSS function specifies an homogeneous 2D transformation matrix comprised of the specified six values. The constant values of such matrices are implied and not passed as parameters; the other parameters are described in the column-major order.
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).

In the 3D space, rotations have three degrees of liberty, describing an axis of rotation. The axis of rotation is defined by a [x, y, z] vector and pass by the origin (as defined by the transform-origin CSS property. If the vector is not normalized, that is the sum of the square of its three coordinates is not 1, it will be normalized internally. A non-normalizable vector, like the null vector, [0, 0, 0], will cause the rotation not to be applied, without invaliding the whole CSS property.

The scale() CSS function modify the size of the element. It can either augment or decrease its size and as the amount of scaling is defined by a vector, if can do so more in one direction than in another one.
This transformation is characterized by a vector whose coordinates define how much scaling is done in each direction. If both coordinates of the vector are equals, the scaling is uniform, or isotropic, and the shape of the element is preserved. In that case, the scaling function defines an homothetic transformation.
When outside the ]-1, 1[ range, the scaling enlarges the element in the direction of the coordinate; when inside the range, it shrinks the element in that direction. When equals to 1 it does nothing and when negative it performs a point reflection and the size modification.

skew()
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The skew() CSS function is a shear mapping, or transvection, distorting each point of an element by a certain angle in each direction. It is done by increasing each coordinate by a value proportionate to the specified angle and to the distance to the origin. The more far from the origin, the more away the point is, the greater will be the value added to it.
Note: The skew() function was present in early drafts. It has been removed and is still present in some prefixed implementations. Do not use it.
To achieve the same effect, use skewX() if you were using skew() with one parameter or matrix(1, tan(ax), tan(ay), 1, 0, 0) for the general way. Note that tan() isn't a CSS function and you have to precalculate it yourself.
Syntax

- Is an <angle> representing the angle to use to distort the element along the abscissa.
- ay
