<div id="aside">      <img src="{{ 'image.jpg' | asset_url }}" alt="" usemap="#map" /> <map name="map" id="map"> <area alt="" title="" href="#" shape="rect" coords="33,110,395,217" /></a> <area alt="" title="" href="#" shape="rect" coords="35,222,395,321" /></a> <area alt="" title="" href="#" shape="rect" coords="34,325,395,397" /></a> <area alt="" title="" href="#" shape="rect" coords="34,401,395,565" /></a> <area alt="" title="" href="#" shape="rect" coords="33,571,399,628" /></a> <area alt="" title="" href="#" shape="rect" coords="33,632,394,775" /></a> <area alt="" title="" href="#" shape="rect" coords="409,127,584,275" /></a> <area alt="" title="" href="#" shape="rect" coords="410,281,586,337" /></a>
