How to make a responsive canvas?

Question

JavaScript

There is a site - tyts

There is an animation made on canvas



At a resolution of 1920, everything is fine, but at lower resolutions, a laptop, a mobile tablet, the canvas does not scale, tell me how to do it?



Codepen does not allow svg to be loaded, but all js is brought here so as not to look for it on the site. How to make it responsive?
