The skewX() Method

The skewX() method skews an element along the X-axis by the given angle.
Syntax: transform: skewX(20deg);
transform: skewX(-20deg);

Output:

The skewY() Method

The skewY() method skews an element along the Y-axis by the given angle.
Syntax: transform: skewY(20deg);
transform: skewY(-20deg);

The skew() Method

The skew() method skews an element along the X-axis and Y-axis by the given angles.
Syntax: transform: skew(20deg, 10deg);

The matrix() Method

The matrix() method combines all the 2D transform methods into one.
The parameters are as follow: matrix(scaleX(), skewY(), skewX(), scaleY(), translateX(), translateY())
