Design docs https://developer.mozilla.org/en-US/docs/Web/CSS/mask Summary CSS mask, and related properties such as mask-image, mask-mode, etc, are used to hide an element (partially or fully) by masking or clipping the image at specific points. This feature unprefixes the "mask" properties (mask, mask-clip, mask-composite, mask-image, mask-mode, mask-origin, mask-position, mask-repeat, and mask-size) and brings the implementation up to spec. Blink componentBlink>CSS <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3ECSS> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility At this stage we have two areas of risk: 1. It is not yet known which implementation changes will be included, and the prototype will help us understand this. 2. There is web compat risk in shipping changes to this existing feature. *Gecko*: Shipped/Shipping Firefox has nearly 100% pass rate on css-masking WPT tests. *WebKit*: Shipped/Shipping Safari has shipped much of the unprefixing of these properties (https://bugs.webkit.org/show_bug.cgi?id=229082), as well as many implementation improvements, but some interop fixes are still in development. *Web developers*: Positive ( https://github.com/web-platform-tests/interop/issues/148) This is part of interop-2023. *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 Goals for experimentation Ongoing technical constraints None Debuggability Basic debugging support with existing CSS support in devtools. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, 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 Flag name on chrome://flagsNone Finch feature nameCSSMaskingInterop Requires code in //chrome?False Tracking bughttps://crbug.com/1418401 Estimated milestones Shipping on desktop 120 DevTrial on desktop 120 Shipping on Android 120 DevTrial on Android 120 Shipping on WebView 120 Link to entry on the Chrome Platform Status https://chromestatus.com/feature/5177265994596352 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
