To hide your site’s header in Builder:
- Select the first piece of Builder content (e.g. your hero image)
- Navigate to the styles tab and give the content a fixed position in the layout section.
- Still in the layout section, give your content a top, left, right, and bottom value of “0”.
- Lastly, scroll down to the custom CSS properties section in the styles tab and add:
Z-index: 10
This will make your content lay on top of your header, hiding it. If your header is still visible, try giving your content a higher z-index (e.g. 100).
