The challenge here is that ASCII case-insensitivity is _quirky_ wrt CSS. Usually ASCII case-insensitivity is used where the value space is also limited to ASCII. But attribute values are *not* limited in this way. So `green` matches `GREEN` but `grün` doesn't match `GRÜN` (it does, however, match `GRüN`). The "ASCII" decoration of the case matching scheme normatively means this and most of us who have been around CSS know about this, but newcomers may be surprised. -- GitHub Notification of comment by aphillips Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/13645#issuecomment-4050216283 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
