Add touch controls to View Online
When I use the website on mobile, everything works fine except for the view online feature.

When I click on view online, the preview is stuck and I'm not able to move around and see the whole map art completely. I also can't zoom in nor out. I tried turning on desktop mode, it still doesn't work. The screenshot above is the only part of the map art I can see, if I try to move and see the other parts, it just doesn't work. It's stuck.
I know this website is intended for desktop (Java version of the game) , so it's not a surprise if I can't use this website on mobile properly.
Though it would be good if the online preview of the map art is downloadable (in png, jpg, or any image format), or just make the online preview on a different tab, made specially for preview only.
