Astro, WCAG Accessibility, CSS Animations & Vanilla JavaScript

I've for the first time tried out a library for the CSS Animations (Animate.css) which I normally make myself. I was wondering what you think is better, make it yourself, or use a library to solve the problem. I always try to make things myself, but it isn't necessary to keep reinventing the wheel, so I thought I'd try this one out and I quite like how it works :)
