Where did I go wrong in my prototype?

Hi! I turned my website wireframe into a prototype within Figma and when I scroll it stays frozen on the top part but shows pieces of the content. I am linking the wireframe. I can’t figure out what’s wrong with it. Help is much appreciated! Thanks!

Hi there,

Thanks for the post! Could you provide more context about what you mean by “pieces of the content”? I’m trying to understand the exact issue you’re facing. Also, if you can share the expected behavior, that would also help us!

Thanks,
Toku
