        <h1>DOM Marker rotation</h1>
        <p>Rotate DOM Marker's content using CSS</p>
    <p>This example shows DOM Marker with SVG icon which rotates every second by 45 degrees.
    <div id="map"></div>
      The DOM node provided in constructor of <code>H.map.DomIcon</code> is cloned and rendered every time a
      DOM marker reaches (is visible within) the map view port. Therefore all manipulation has to be done
      in <code>onAtach</code> callback where the currently displayed clone reference is available.
      The API manipulates position of rendered DOM element (e.g. when panning the map, zooming the map, etc.) by changing
      the <code>transform</code> CSS property of the <code>clonedElement</code>. Therefore in order to rotate DOM icon,
      we need to manipulate its child node <code>transform</code> CSS property (in our case SVG node).
