Revision 1131023 of rotate()

<div>{{CSSRef}}</div>

<p>The <code>rotate()</code> CSS function defines a transformation that moves the element around a fixed point (as specified by the {{ Cssxref("transform-origin") }} property) without deforming it. The amount of movement is defined by the specified angle; if positive, the movement will be clockwise, if negative, it will be counter-clockwise. A rotation by 180° is called <em>point reflection</em>.</p>
