Is there any way for the course to start in Fullscreen?
Or how do I create a button on the course itself that makes the screen fullscreen.
I need to eliminate the taskbar by placing all the buttons within the course itself.
Sorry for my bad english.
Sistem: Windows 7
Is there a way to force the screen to rotate to landscape mode?
Yes but it only works on Android devices (tested on Chrome browser).
var promise = screen.orientation.lock('landscape');
It also requires user interaction and the page is already in fullscreen mode.
So for cross devices, you should inform the viewer to do rotate the screen. For example: display a text message on the first slide, or design a portrait layout with just the message.
