Usage

AOS set animation by using data-aos attribute:

1<div data-aos="fade-in"></div>

And adjust behavior by using data-aos-* attributes:

 1<div
 2  data-aos="fade-up"
 3  data-aos-offset="200"
 4  data-aos-delay="50"
 5  data-aos-duration="1000"
 6  data-aos-easing="ease-in-out"
 7  data-aos-mirror="true"
 8  data-aos-once="false"
 9  data-aos-anchor-placement="top-center">
10</div>

You can also use AOS with Markdown block attributes in the content file, which is more convenient than creating shortcodes sometime.
