transform: skewX(0);

transform: skewX(35deg);

transform: skewX(-0.06turn);

transform: skewX(0.352rad);

</section>

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 angle representing the angle to use to distort the element along the abscissa (horizontal, x-coordinate).
