Hi there,
you could use the Header Element and set the Site Header to merged, but as you’re using Elementor probably easier to use some CSS. Edit the Elementor Section > Advanced Tab > CSS Classes and give it a custom class e.g: full-height-hero
Then add this CSS:
@media (min-width: 768px) {
.full-height-hero {
height: calc( 100vh - 60px );
}
}
The 60px is the height of the nav
May need to give that property some !important
