Hi there,
I’m new to GP and GB and I’m trying to do the same. On a new page I’ve set the “Content Container” to Full width. Inside the page I put a GB Container and set the minimum height to 100vh. The background of this Container is a huge hero image. But the problem is the navigation bar on top of the page. This navigation bar comes first and after that the Container with the hero-image begins. Is it possible to integrate the navigation bar into the Container, so that there is a full viewport hero?
