Re: [csswg-drafts] Browser zoom unit for accessibility [css-values-and-units] (#6869)

Thanks @cookiecrook

Maybe I’m misunderstanding you here but isn’t this expectation the opposite of what happens currently with browser zooming? This issue is aimed to resolve this disconnect between expectation and reality.

Here is an example that illustrates the issue particularly well. It uses the new `qi` units for font scaling so you’ll need Chrome Canary with the container query flag to view it.

- [Without a zoom unit](https://cdpn.io/scottkellum/debug/jOwmOZE)
- [With a zoom unit (hacked together with JS)](https://cdpn.io/scottkellum/debug/45e92731418bbc1ed052e880b530dfc2)

The reason why the text is set up to scale this way is to create a dynamic visual hierarchy on the page, but as zoom is changed the visual hierarchy changes also get triggered. This is a common problem with scaling text by any means, particularly responsively with viewport units,  and will become more egregious as we deal with the more complex design space that container queries occupy.
