Div won't remain sticky

Hi there,

I’m trying to create an effect similar to this section on this site.

I’ve tried to create a div within a section that is sticky, and then create the animations relative to the section scroll. However, the div won’t remain sticky no matter what I try to do. How can I fix this?

This is the section I’m trying to work with.

You can see the site here:

Thank you!
