How to make this animation?

Look at the following two websites of which one of these is my school website.
Link.
And another website:
react.org
In these two websites when we scroll down and reach a part of the page, the content flys up and stops.

I want to know how to make this animation. Can anyone please answer me with the code and live preview??

Thanks in advance!!!
