View source for P5JS look like an mobil app

[[File:Phone.png|100px|right]]

'''To make p5*js look like an app''', there are three issues. 
# How do I recognize a mobile device? 
# How do I activate the full-screen view? 
# How do I simulate the phone on the desktop computer?

This tutorial shows P5JS Sketches on a mobile device in full screen portrait mode and on the desktop computer in landscape mode the canves is displayed inside a mobile phone frame. Because the deviceOrientation command does not work reliable to detect a mobile devices, this tutorial will look at the height and width ratio.

Applications in landscape mode must reverse these conditions.
