Tutorials for mouse interaction without Elementor/Webflow?

Hi there,

I very much dislike the “software a service” model in general, but especially when it comes to web design. That`s why I am trying to avoid Webflow and Elementor.
Nearly all tutorials that cover mouse interaction are build around them, though.
Does anybody have seen good learning material for creating lottie interaction without the need to use those two systems?
I want to mainly do mouse over, color changes, pop ups.
