Why aren't my animations working?

I’m using Animate.css in CodePen but none is working https://codepen.io/CeciPeque/pen/PgVzxr what am I doing wrong?

I’m seeing this everywhere

class="os-animation" data-animation="fadeInUp"

the class should be aos-animaton, please check and verify if it solved the issue!

yes it should be “aos-animation”, thanks that solved the problem, I had an older version sorry.

No sorry but actually didn’t solve it, the images and text now appear but without any animation D:
