Hello, this comment applies to the related transformation function in css3-3d-transforms as well. http://www.w3.org/TR/2009/WD-css3-2d-transforms-20090320/#transform-functions http://www.w3.org/TR/2009/WD-css3-3d-transforms-20090320/#transform-functions I would like to know, which matrix is represented by skew(<angle> [, <angle>]). Currently is is noted a reference to SVG SkewX, what is obviously not applicable for two angles, respectively there is no difference to SkewX and the second angle is redundant. In general skewing or shearing is always related to one direction and can be represented for example with a matrix a b c d with: a+d = 2 ad-bc = 1 (the determinant) Is it possible to provide a relation between the skewing angle and skewing direction and the matrix components and the two angles in the definition? A useful interpretation could be, that the second angle describes the angle between the x-axis and the skewing direction (0 degree is the same as SkewX, 90 degree is SkewY and so on), but the prose does not indicate such a relation. Best wishes Olaf
