Hello, I have a working Code for a scroll animation using a Sprite Sheet image, filling up the entire viewport as desired.  But I would like to make one in a Next.js or React.js code.  I would post my Next.js progress, but nothing is working anyway.   I am having issue with making the JSX acknowledge the DOM with "useRef", and trying to work around "new Image" with something else in Next.js.   Help would be appreciated. Below is the working code: HTML:
