Learning AOS (Animate On Scroll) library

Just one of the things I'm learning. https://github.com/hchiam/learning

Where I first heard about it: https://css-tricks.com/aos-css-driven-scroll-animation-library

The library itself: https://github.com/michalsnik/aos

My fork of the anchoring triggers example: https://codepen.io/hchiam/pen/MWywwdm

My fork of the example of custom animation triggered by scroll position: https://codepen.io/hchiam/pen/MWywwdo

My SCSS learning repo: https://github.com/hchiam/learning-sass

Example

<div
  data-aos="fade-left"
  data-aos-anchor="#trigger-2"
  data-aos-anchor-placement="top-center"
></div>

In this example:

• data-aos = animation effect(s) on the div it's on (e.g.: fade-left = fade in and move in left-wards).
• data-aos-anchor = triggered by element with the id trigger-2.
• data-aos-anchor-placement="top-center" = top of #trigger-2 at the center of the window will trigger the animation.

Also:

• data-aos="custom-animation" = use custom CSS styles for before ([data-aos="custom-animation"]) and after ([data-aos="custom-animation"].aos-animate)
