CSS Reference Function

skew()

The skew() function is a 2D transform function used to skew an element.

Skewing an element is like applying a tilting effect on it. It is like grabbing two opposite vertices of a rectangle and then pulling them in opposite directions, turning the rectangle into a parallelogram.

It takes either one or two arguments: ax and ay. Both are angle values. The first value (ax) skews the element along the x-axis, and the second argument (ay) skews it along the y-axis. Skewing along the x-axis is like pulling the rectangle angles to the sides, and skewing along the y-axis is like pulling them vertically in opposite directions. The two angle values determine the amount by which the element is skewed. If the second value is not provided, it is assumed to be zero.

The skew() function was present in early drafts. It has been removed but is still present in some implementations. *Do not use it*. In order to skew an element in either direction, use the skewX() and skewY() functions listed in the main entry about the transform property. Also note that the behavior of skew() is different from multiplying skewX() with skewY().

The official syntax looks as follows:

transform: skew(<angle> [, <angle>]?);
                

For a better understanding of the transform functions, please refer to the transform entry.
