1611575 - Should vertical-align:middle behave differently when the dominant baseline is not alphabetic?

Status: NEW

Description

[Mozilla Apprentice]

Resolutions were made for csswg-drafts/#4495.

Should vertical-align:middle behave differently when the dominant baseline is not alphabetic?

• RESOLVED: "vertical-align: middle" always uses halfway between alphabetic baseline and x-height, except in modes where the x-height is meaningless (vertical writing modes with upright text orientation)
• RESOLVED: In such "meaningless" cases, "middle" means the same as "central".

See discussion linked above. More generally, we don't yet support all the values for vertical-align baselines defined in https://drafts.csswg.org/css-inline-3/#alignment-baseline-property: there's not just middle but also central and center, each with a slightly different meaning.
