Hi @sherlyntandinata, thanks for your reply. It looks like you have a lot of content nested within the overlay, I would recommend to move the portfolio works div and nested elements as a sibling to the Overlay in the navigator and update some of the overlay styling:
- Restructure the content so that the fixed nav is just under the body:
- Update the Overlay to be position absolute with a full cover and z-index of 5:
- republish site and check the results.
Let me know if this helps
