Simple AOS animation without any jquery library. || HTML || CSS || Javascript

This is my another repository about aos (Animation On Scroll).
Some people thinks that animation on scroll is only possible by jquery plugin or only plugin. But I think different. I am on a mission on doing everythihg without any plugin but only vanilla javascript. So, in this attempt, I have made a new file on aos. By following these instruction, you can be able to make cool animations trigged by scroll event.
