Developers can specify a length value to round polygon corners without manually computing bezier curves. Interactive demo: https://codepen.io/yisi/pen/NPRLEQN CSSWG issue: https://github.com/w3c/csswg-drafts/issues/9843 *Blink component* Blink>CSS <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECSS%22> *Web Feature ID* shape-function <https://webstatus.dev/features/shape-function> *Motivation* Rounded polygons are a common design pattern on the web. Without this feature, developers who want rounded corners on a polygon shape must manually compute bezier control points or use workarounds such as SVG clip paths. The polygon() round parameter makes this directly expressible in CSS, reducing complexity and improving maintainability. *Initial public proposal* *No information provided* *TAG review* *No information provided* Did TAG ever look at this? *TAG review status* Not applicable *Goals for experimentation* None *Risks* *Interoperability and Compatibility* *No information provided* *Gecko*: No signal (https://github.com/mozilla/standards-positions/ issues/1197) *WebKit*: No signal (https://github.com/WebKit/standards-positions/ issues/474) *Web developers*: No signals *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? *No information provided* *Debuggability* *No information provided* *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 Could you also please link to WPTs here?
