skewX()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

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

Try it

transform: skewX(0);

transform: skewX(35deg);

transform: skewX(-0.06turn);

transform: skewX(0.352rad);

<section>  <img          src="/shared-assets/images/examples/firefox-logo.svg"    width="200" /></section>

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

Note:skewX(a) is equivalent toskew(a).

Syntax

css

skewX(a)

Values

a: Is an<angle> representing the angle to use to distort the element along the abscissa (horizontal, x-coordinate).
