Summary
Chrome has added support for two features that allow sites to size fonts in proportion to the operating system/browser text scale settings:
<meta name="text-scale" content="..." />element, which was added in Chrome 146, and works across Desktop and Mobile platforms. See https://chromestatus.com/feature/5112244702674944. As far as I can tell, this has full support, but that support varies depending on the text sizing functionality available in OS/browser combination being used. I'm intending to document these in as much detail as possible in the content update.preferred-text-scaleenv()variable, which was added in Chrome 138. This allegedly works only in Android, but it also seems to have somewhat of an effect in Chrome desktop, which I am still investigating, and wish to write up in the content. As a result, I've listed it as supported on desktop too.Test results and supporting details
