I am trying to make a web application that is 100% of the screen width and 100% of the screen height, with a 16:9 aspect ratio. It would be awesome if I would be able to view this website fullscreen on my tablet, but unfortunately the on-screen toolbar takes up a large amount of space, making my website display neither in full height nor in full width:
Now I know that since recently, it is possible to hide the scrollbar by scrolling the page down (source). However, since my web application is 100% high, I am unable to hide the toolbar this way.
I was wondering whether anybody had another idea as to how I would be able to hide the toolbar. A CSS-only (or perhaps some HTML meta tag unknown to me) method is preferred, but I will settle for a technique using JavaScript as well.
