Hey, thanks for the link 
I’ve noticed that you’re duplicating your content multiple times to “fit” it within the page. What I would instead suggest, is to contain that content within one section, eg:
Section
|— Image
|— NavBar
Section
|— Heading
|— Author image
|— Text
Section
|— Footer
You can easily fit the content nicely on each media query with Style panel. Below is the video on how I achieved it 
oops, wrong link. Uploading new one…
I’ve also noticed that your’e using both display
settings

as well as Visibility Settings

Which never is a good combination. I’d strongly suggest using only display
settings here for future cases. Although going with only one block of content that is styled nicely on all pages, would be a much better solution. It would also go well with the search indexing, because you wouldn’t have duplicated content on same page.
Cheers,
Bart
