The rotate() CSS function defines a transformation that rotates an element around a fixed point on the 2D plane, without deforming it. Its result is a <transform-function> data type.

The axis of rotation passes through an origin, defined by the transform-origin CSS property.

Syntax

The amount of rotation created by rotate() is specified by an <angle>. If positive, the movement will be clockwise; if negative, it will be counter-clockwise. A rotation by 180° is called point reflection.

rotate(a)

Values

a
Is an <angle> representing the angle of the rotation. A positive angle denotes a clockwise rotation, a negative angle a counter-clockwise one.

Examples

HTML

<div>Normal</div>
<div class="rotated">Rotated</div>

CSS

div {
  width: 80px;
  height: 80px;
  background-color: skyblue;
}

.rotated {
  transform: rotate(45deg); /* Equal to rotateZ(45deg) */
  background-color: pink;
}
