The basic idea of the compromise is to design the p5js app for a 16: 9 portrait format. This saves you the work of having to develop an adaptive design. The remaining area on the desktop computer is filled with a background pattern. The full display height is used on the mobile phone, so you can easily see the app full screen if you push the URL bar up a bit. (Unfortunately, the full screen command does not work on iOS devices.)

Background Pattern

Download the Stripe.png or design your own background tile.

Html Code

Add this to your Html header

  <meta name="viewport" content="user-scalable=no,initial-scale=1,maximum-scale=1,minimum-scale=1,width=device-width">

  <style>
    body {
      background-image: url('stripe.png');
    }

p5js Code

Add this to your p5js code into setup

  // go 16:9
  if (windowWidth < windowHeight) { 
    // if portrait=mobil then use the full display height
    createCanvas(displayHeight * 0.5625, displayHeight);
  } else {
    // if landscape=dektop then use the full window height
    createCanvas(windowHeight * 0.5625, windowHeight);
  }

And add this function to your p5js code

function windowResized() {
  // go 16:9
  if (windowWidth < windowHeight) {
    // if portrait=mobil then use the full display height
    resizeCanvas(displayHeight * 0.5625, displayHeight);
  } else {
    // if landscape=dektop then use the full window height
    resizeCanvas(windowHeight * 0.5625, windowHeight);
  }
}
