At the Unlevel site I am trying to set up the first section of the homepage to “fit to screen”, but its too long and the problem I think I am having is that I am not allowing for offset site header height. How do I do that?
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
