Sizing hero section - complete beginner

Hey Vincent!

Also a complete novice here - I’m trying to build my intro page with the section taking up the entire vp, no scroll. It appears as if I have succeeded because none of my breakpoint pages scroll.

However, in designer & on preview, the smartphone page appears so long [beyond 100% height] even though it does not scroll.

Is this a Webflow default appearance? Do I need to publish the page to see the live viewport?

Thank you!
