Problems with quark theme on mobile

Anyone know why the Quark theme One Page Demo Site looks so much better on mobile than when you actually download the theme? The hero module takes up the whole page instead of just the top half. I’m sure it’s just a CSS issue but I’m new to Grav and not sure where to start. See below for screenshot comparison. Thanks!

Did you download the skeleton for the one page site? There may have been some changes made to that particular example.

Yep, that’s the skeleton with no changes immediately after downloading vs the demo.
