I'm using Horizon template and trying to get my homepage index banner to display a full bleed video on computer screens and full bleed fallback image on mobile devices. In Site Styles I've been able to change the Index Overlay Padding to 22% which seems to give me full bleed video on all desktop and laptop screens. But it looks small and terrible on mobile.
Is there either code that I can inject that will force full-screen for index banner site wide on all devices. Or code that would allow me to set separate Index Overlay padding values for desktop and mobile versions?
Any help would be much appreciated.
