js_url

Similarly, this parameter is used to specify the URL of AOS JavaScript, feel free to replace it with whatever CDN you like.

AOS Options

To tweak the AOS options, you’ll need to create the assets/mods/aos/js/options.ts file in following form.

1export default {
2  delay: '1s'
3  // ...
4}

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.
