Specification

https://drafts.csswg.org/css-ruby/#ruby-overhang

Summary

Support of new CSS property `ruby-overhang` is added. The property accepts one of `auto` and `none` keywords, and controls overhang of ruby annotation text.

Blink component

Blink>Layout>Ruby

Web Feature ID

ruby-overhang

Motivation

A ruby annotation can sometimes obscure adjacent content when it overhangs. The ruby-overhang property gives authors a way to disable this behavior and prevent unwanted overlap.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
