skew()

The skew() CSS function is a shear mapping, or transvection, distorting each point of an element by a certain angle in each direction. It is done by increasing each coordinate by a value proportionate to the specified angle and to the distance to the origin. The more far from the origin, the more away the point is, the greater will be the value added to it.

Syntax

skew(ax)       or
skew(ax, ay)

Values

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

Examples

Using a single x-angle

HTML

<p>foo</p>
<p class="transformed">bar</p>

CSS

p { 
  width: 50px;
  height: 50px;
  background-color: teal;
}

.transformed {
 /* the same as skewX(10deg); */
  transform: skew(10deg);
  background-color: blue;
}

Result

Using two angles

HTML

<p>foo</p>
<p class="transformed">bar</p>

CSS

p { 
  width: 50px;
  height: 50px;
  background-color: teal;
}

.transformed {
  transform: skew(10deg, 10deg);
  background-color: blue;
}
