I have a JavaScript function on my mouse that when you move it, sparkles fall from it and it looks amazing! However, I’d like it to stay within the hero section only of my webpages… I don’t mind it being on the entire page because it’s so subtle that it doesn’t really get in the way but the problem is that since applying it, my pages seem to have an indefinite scroll… I’ve tried wrapping the section of code in a div, I’ve tried setting a specific height for the page, I’ve tried adding !important to override whatever it is that makes the page scroll on and on… If I can’t figure out how to make it stop scrolling, how can I apply it to just the hero image? Here is my code… It’s quite alot but I’m not sure what it is exactly that you’d need to see to find the problem.
