thread is closed and so here is a solution
my solution was incomplete but now this is the right way:
– perhaps you move my answer to that thread.
put in the hotspot image into a color-section. Set an ID to Color-section e.g. #something
than quick.css :
#something .container, #something .av-hotspot-container {width: 100% !important}
#something .av-hotspot-container img {width: 100% !important}
