How do I make my canvas look the same on other devices?

Hello,

How do I make my canvas look the same on all devices?
 

function PixiPlay(){
    var renderer = PIXI.autoDetectRenderer(350,460,{antialias: false, transparent: false});
    document.body.appendChild(renderer.view);
    var root = new PIXI.Container();

I saw a tutorial talking about Pixiv4.
But he talks almost nothing about the canvas 

Can anyone teach me how to do this, in a simple way, please?
