Hi all, I'd like to announce an Intent to Prototype for:
- *Feature name:* Layout Instability Attribution in CSS Pixels - *Contact:* anediaz@gmail - *Explainer:* https://github.com/anediaz/layout-shift-attribution-in-css-pixels/blob/main/Explainer.md - *Summary:* The Layout Instability API currently reports attribution rectangles (`prevRect` and `currentRect`) in device pixels, which vary based on resolution and `devicePixelRatio`. This change proposes reporting them in CSS pixels for consistency with other layout and performance APIs. - *Motivation:* This will align attribution with other Web APIs, such as `getBoundingClientRect()` and make layout shift data easier to visualize, debug, and combine across devices and tools. - *Initial public proposal:* https://issues.chromium.org/issues/399058544 - *TAG review:* Not yet requested - *Risks:* None known. This change only affects how attribution data is reported, and is gated behind a runtime flag. - *Interoperability:* - Mozilla: No signal - WebKit: No signal - *Estimated milestones:* N/A (this is a prototype only) - *Footprint:* This will be implemented behind a runtime flag. - *Link to entry on Chrome Platform Status: * https://chromestatus.com/feature/5155103518228480 This Intent is to begin prototyping the feature and gather feedback. Thank you for your help and time. Cheers, Ane Diaz de Tuesta -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
