Sorry, I don't do code, please show me where to edit the width and height to 100%, thanks.
Moved to Offtopic.
Anyway these links could help ( but they don't cover CSS Grid) :
I don't do code, all I need is the exported HTML from Armory to be full page and responsive.
I added a convenience way to achieve this - set Properties - Armory Project - Window to Fullscreen.
Properties - Armory Project - Window
To update, download the latest armory from itch.io (v0.1b if you are on Windows) and then use the updater: http://armory3d.org/manual/dev/gitversion.html. Then you should be all set and Armory will play taking the full page size available.
Wow, thank you very much!
