Example of web page:
Click on the right selection box and select “Danuvius-Haus”. Normally, a blinking mark should appear within the visible screen area. But on a phone with a screen width of e.g. 360 px the map does not scroll to the left, so you have to do this manually in order to see the blinking square.
Using Firefox Mobile or Chrome, the horizontal scroll does work correctly on the same device. Also, no problem on a tablet when the screen is wide enough for the map.
