Need help! What needs to be added in the script.js or css file so that the animation does not move when the page is scrolled?

Ummm, if in a quick way, then, although I don’t understand why body has position: absolute, and much more, then this:
Give the body tag background-color: #0c0c0c; margin: 0;
Change the canvas tag from position: fixed to position: absolute;
