skewX()

{{CSSRef}}

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

{{EmbedInteractiveExample("pages/css/function-skewX.html")}}

This transformation is a shear mapping (transvection) that distorts each point within an element by a certain angle in the horizontal direction. The abscissa (horizontal, x-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 {{cssxref("<angle>")}} representing the angle to use to distort the element along the abscissa (horizontal, x-coordinate).
