Vertical Scroll in two blocks

hi! i want to recreate this effect : https://briannepoulinet.com/

How can I do that?

there are a few ways though:

you could have to groups. One for left and one for the right panel.
The elements of each group are lined vertically. Now fix each group to the left upper corner so you have your starting view you like. Now set up on scroll animations for each group. the left is moving up and the right is moving down.

As you cannot set the animation to a fixed group in all there is the function to copy the animation and paste it onto another so you don´t have to set up every element manually.

This would also work if the groups are not fixed. but then only one group needs an animation, as you are already scrolling down the one panel.
