I wish there was a CSS media query for the user’s scrollbar preference. macOS has three options for when to show scrollbars:

- Automatically based on mouse or trackpad
- When scrolling
- Always

I set mine to “Always” (even though many native apps including Setapp and Apple Music ignore it and disappear them anyway).

But it would be nice for web apps to know the user’s preference.

Screenshot of the macOS Appearance setting. I’m highlighting the scrollbar section I described in the post.
