Worldmap fullscreen

I have worldmap opened in chrome on a touchscreen, to show GPS positions. Works perfectly.
Does anyone have any idea how to force fullscreen ?
I don't want users to be able to browse to an other webpage or close chrome.
Sorry if the answer is too obvious, I really made an effort to find a solution...

By the way, Node Red is top, love it !

Don't think you can do this from client side script.

What you likely need is kiosk mode. Search Google for kiosk mode for your PC operating system. There are various options for all systems.

Correct - you can't do this client side - it must be a user initiated action. So you have to start in kiosk mode.

Ok, thanks
