If you mean the "Hide scrollbars" note, I agree 100% (:

There are a few specific situations where it can be useful, but I added the caveat precisely because it’s generally not a good practice.

re scrollbars, Can you give an example?

An online game for example.

Sure. I was thinking of fairly narrow cases, not ordinary page scrolling:

- A swipe/drag carousel with visible arrows or dots, especially a looping carousel where the native scrollbar does not represent a meaningful start and end

- An accordion or expanding panel that animates to reveal all of its content. During the transition, its intermediate height may briefly produce a scrollbar (and a visual flash), even though the fully expanded state does not need one

- Highly visual or experimental interfaces where scrolling is communicated through another control, or where the scrollable area is decorative and scrolling is not required to access the content
