Explainer https://davidsgrogan.github.io/env-explainer.html Specification https://drafts.csswg.org/css-env-1/#text-zoom Summary Exposes a user's preferred font scale to CSS. Currently, it is not practical for a page to detect if the user has changed their preferred font size via the Operating System's preferences. This CSS environment variable will reflect the scale chosen by the user. Blink component Blink>Accessibility TAG review https://github.com/w3ctag/design-reviews/issues/1101 TAG review status Pending Risks Interoperability and Compatibility None Gecko: No signal (https://github.com/mozilla/standards-positions/issues/1229) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/499) Web developers: Positive (https://github.com/w3c/csswg-drafts/issues/10674) This proposal started with a request from a BBC developer Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability This can be debugged using existing devtools support by connecting to a device. We have a plan for making this easier at https://crbug.com/419595584. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No Initial support will be limited to Android, which has limited practical ability to respect the OS font scale today. On Windows, we scale the entire browser in response to the OS setting, and some followup work is needed to support this while not double-zooming. Is this feature fully tested by web-platform-tests? Yes This is tested with internal WPT tests due to lack of support for OS font scale setting in tests. https://github.com/web-platform-tests/wpt/issues/12725 Flag name on about://flags None Finch feature name CSSPreferredTextScale Rollout plan Will ship enabled for all users Requires code in //chrome?

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way). https://github.com/w3c/csswg-drafts/issues/10674 Link to entry on the Chrome Platform Status https://chromestatus.com/feature/5328467685801984?gate=6195643460354048 Links to previous Intent discussions Intent to Prototype: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/CAOZbSt1dSWUwuFD%2Bu%3DwGXf-ubdgh8K%3D0oj13%3DkrvADSOM41xtw%40mail.gmail.com This intent message was generated by Chrome Platform Status. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
