When screen size is reduced or increase design is not show in proper layout

Hello,

Currently I am creating a page and I have a issue like when the screen size is reduced or increased the design gets messed up. in this section i am using scrollify and position sticky.

I have set different VH in this section To set this type of animation. But When i open the link in laptop or PC with small screen or screen size is reduced or increased , the design gets messed up. So how do I solve this?

Thank you.
