The only sticky headers I like are the ones that disappear while scrolling to the bottom of the page but reappear when scrolling back up. Preferably while scrolling up the user is only seeing the navigation and logo. Otherwise, they're super annoying.

These are just as bad, at least their default implementation that triggers on tiny up movements as it covers content you tried to re-read or just annoyingly pops up on inadvertent finger movements

Unless you're reading at the top of the screen (i.e. on a phone), scroll up to recap on something you missed, and then the header slides in and covers the exact thing you were trying to read.

Bonus points if the header is absolutely massive and takes up a full fifth of the innerHeight.
