Specificationhttps://github.com/whatwg/html/issues/8413 Summary CSS property writing-mode allow elements to go vertical, but users cannot set the direction in which value changes. With this feature, we are allowing the form control elements meter, progress and range input type to have vertical writing mode and choose the form control's value direction. If direction is rtl, the value is rendered from bottom to top. If direction is ltr, the value is rendered from top to bottom. For Web compatibility, we plan to slowly rollout the change in 123 and enable in stable in 124.

(12072686) *Web developers*: No signals *Other signals*: Ergonomics No, there are no other platform APIs this feature will be frequently be used in tandem with. Activation It should not be challenging for developers to take advantage of this feature immediately as it is simply using the CSS properties on the desired form control elements. Security This is a form control feature and I don't expect security risks. 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? There are no WebView specific changes with this feature. Debuggability This feature is debuggable by trying to access the form control element's writing-mode and direction CSS values in DevTools. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes https://wpt.fyi/results/css/css-writing-modes/forms?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned&view=interop&q=label%3Ainterop-2022-forms%20or%20label%3Ainterop-2023-forms Flag name on chrome://flagsFormControlsVerticalWritingModeDirectionSupport Finch feature nameFormControlsVerticalWritingModeDirectionSupport Requires code in //chrome?False MeasurementNone Availability expectationFeature is available on Web Platform mainline within 12 months of launch in Chrome. Adoption expectationFeature is considered a best practice for some use case within 12 months of reaching Web Platform baseline. Adoption planWe plan to release this feature in milestone 124 (Finch in 123). Safari has already implemented this feature. Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? No Estimated milestones Shipping on desktop 124 DevTrial on desktop 123 Shipping on Android 124 DevTrial on Android 123 Shipping on WebView 124 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
