How to make background image for the entire page?

Hi there,

It's just using Fixed position: https://docs.generatepress.com/article/backgrounds-overview/#attachment

Let me know if this helps :)

Yes. I saw the fixed option. However, each section has background options for the selected element. I want one continuous background image across all the elements.

That would be the body background image option in the customizer:

I added the image there, but it is not displaying above the navigation header. It shows white. https://staging6.saltwater-recon.com Thanks.

Change your header background color to transparent:

Awesome! Thanks. How can I center the main logo in the header?

This should help: https://docs.generatepress.com/article/header-layout/#header-alignment

Perfect! Thanks. How can I get the nav menu to display like this on mobile to where the logo appears when you scroll down and stays sticky with the menu drop down on the right instead of being centered? Thanks.

Could you open a different topic(s) for separate question(s)?

Thanks!

Sure. Sorry about that.

No problem :)
