full-width template

Hello, and first off I love this theme, it’s simplistic/clean design gets 2 thumbs up here!

Question: I’ve been attempting to create a full-width page template (through my child-theme, creating a custom page.php and changing features, along with tweaking some things in the style.css) but nothing has worked!

I don’t know what I need to change (and where I need to change it) in this theme to be able to make it truly full-width on a desktop computer, instead of the boxed layout (and no i’m not talking about the boxed/fullwidth layout option in customizer)

if anyone could guide me in how to get a true full page template, I would greatly appreciate it!
