The skewX() CSS function defines a transformation that skews an element in the horizontal direction on the 2D plane. Its result is a <transform-function> data type.

skewX(a) 

skewX()

The skewX() CSS function defines a transformation that skews an element in the horizontal direction on the 2D plane. Its result is a <transform-function> data type.

This transformation is a shear mapping (transvection) that distorts each point within an element by a certain angle in the horizontal direction. The abscissa coordinate of each point is modified by a value proportionate to the specified angle and the distance to the origin; thus, the farther from the origin a point is, the greater will be the value added it.

Note: skewX(a) is equivalent to skew(a).

Syntax

skewX(a) 

Values

a

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