What this video covers
"Above the fold" is whatever's visible before you scroll - borrowed from newspapers folded in half on the stand. It still matters because the first screenful gets the most attention and sets whether people stay - but the fold isn't a wall: people do scroll, and the line itself moves with every screen size.
Drag the fold up to a short screen and your call-to-action slipped below it - unseen unless someone scrolls. Drag it down and the top felt cramped, everything fighting to be "above the line". The content never changed; only the fold did - which is exactly why it's a priority cue, not a boundary to obey.
