Side note: it's not strictly possible to have each browser support the OSes typographic conventions: To do so, macos browsers would all set opsz=16 for 12pt since one macos point is 1 CSS px, thus 4/3 CSS pt, and Windows browsers should set opsz=12 for 12pt since on 1 OS point = CSS point and 1 DIP = 1 CSS px. Of course, we can't do that because we wouldn't have cross-platform consistency. I believe this is why Firefox chose to have consistency, by supporting the macos typographic convention on all platforms, even Windows. That's not strictly honoring the host OS convention, but honoring the macos convention. I guess my proposal comes down to this: do you set opsz to one OS point, or one CSS point? The former might have internal consistency on macos, but is inconsistent with print-based applications and, strictly speaking, browsers on other OSes (unless they adopt one macos point). The latter would be consistent amongst other OSes and print apps, but forces macos to break consistency and adopt a Windows point. The real culprit is history: if the web had adopted macos conventions, then we'd be having this exact same conversation, with the roles swapped. -- GitHub Notification of comment by robmck-ms Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4430#issuecomment-548914023 using your GitHub account
