Thx for your comment! I agree completely that GSAP isn't beginner-friendly and because Animate.css is such as big success, there's a clear need for cool "just add some water" web animations that only requires adding an HTML class name and the inclusion of my JS repo (minimized, eventually, or just adding a few effect snippets you want to include in a project).
PS, there are multiple ways to select / target elements, even using just document.getElementsByClassName(names), but I'm currently not sure if I want to support more advanced yet easy-to-use selections later on in development. SizzleJS could be an idea to use, so could D3JS or jQuery itself, or I could just strip jQuery out completely. Let's see, I don't think including a bunch of overhead-code this size makes a big impact on performance, but in case it does - eventually - I'll look into it! ;-)
Edit: self-upvoted for context-visibility (the Steemit interface could / should deal with that as well... because I wrote such a long reply to @julieNBH's comment, this reply of mine to @sambillingham completely lost visual context... Maybe we can partially auto-collapse long comments, or add some UI element to "group" comment threads that belong together...)
