> The jutting into interlinear space is showing how gridding in J layout is needed to keep the line leading (as measured from the line centers) constant even in the face of larger sized text. Yes. Agreed. But the example in [figure 301](https://www.w3.org/TR/jlreq/#fig3_5_1) makes this barely noticeable: it is not easy to see in the example-image. My request in this issue is to have an example of sideways-ed Latin text within a vertical Japanese line box in the "Requirements for Japanese Text Layout" document. > we need a system whereby the markup could specify which script (set of metrics and behaviors) is dominant, so all scripts in the line follow the rules of the dominant system. (...) such a mode in CSS doesn't exist, at least in the way I was trying to describe. Such system exists in CSS. [CSS3 Writing-modes, section 4.2](https://www.w3.org/TR/css-writing-modes-3/#text-baselines) "In vertical typographic mode, the central baseline is used as the dominant baseline when 'text-orientation' is 'mixed'" In horizontal typographic mode, the alphabetic baseline is used as the dominant baseline. And the typographic mode is given by 'writing-mode' [CSS Writing Modes 3, section 3.2](https://www.w3.org/TR/css-writing-modes-3/#block-flow) [CSS Writing-Modes 4, section 3.2](https://www.w3.org/TR/css-writing-modes-4/#block-flow) Also, [dominant-baseline property](https://www.w3.org/TR/css-inline-3/#dominant-baseline-property) when implemented will allow web authors to specify 'hanging' or 'ideographic' if that is what they want. -- GitHub Notification of comment by TalbotG Please view or discuss this issue at https://github.com/w3c/jlreq/issues/246#issuecomment-742195734 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
