Holy hell that website is awfully designed. Why does it try to snap my scrolling position to what it thinks is the right position? It doesn’t even work, it jumps around like hell, I try to click through the examples and it just kicks me to the bottom. This is exactly the same idiocy of bad and unaccessible design for aesthetic purposes that the site complains about. The irony is palpable.

That's one issue.

Another is how some people seem to think that you can only put one idea on the screen at a time, and users should scroll scroll scroll.

Both OP and your link both commit that sin.

Just put everything on one page and let my eyes do the moving.
