Issues with sticky position and overflow

Issues with sticky position
Hey, guys!

I have got a problem with sticky position on landing page.

I intend to set sticky position on “testimonial selection section”.
As far as I know, sticky position doesn’t work on overflow’ hidden’, so that body section is set to overflow: visible…

But the main point is that I wish to set other sections overflow: hidden only except for “testimonial selection section”…because especially footer section with overflow: visible seems like weird and not professional…

Is it possible ?

Thank you so much indeed in advance!
