Specification

https://drafts.csswg.org/css-ruby/#ruby-align-property

Summary

A new CSS property `ruby-align` is added. The property accepts one of `space-around` `space-between` `start` and `center` keywords, and controls alignment of ruby base text and ruby annotation text.

Blink component

Motivation

There are multiple ways to align characters when the length of ruby annotations and the base characters do not match, and the `ruby-align` property allows web authors to choose among them.
