Thanks for the quick reply!
I’m afraid I’m still a bit confused. On the demo homepage, is that a static page you’re using for the homepage? http://demo.generatepress.com
If so, how do the articles appear below the large full-width header on your homepage, or are they hard-coded into the static page somehow?
Also, in Settings there is a “Blog Page Header” which puts an image at the top of the homepage, but, it’s not full-width. Is that different from the Page Header add-on?
