Microsoft Edge announces participation in Interop 2025, a collaborative effort with Apple, Bocoup, Igalia, Google, and Mozilla to improve web platform interoperability.
Interop ensures that code written for the web works the same way across different browsers and devices, focusing on resolving bugs and driving full interoperability.
In 2024, Interop resolved issues in areas such as Popover API, declarative shadow DOM, CSS nesting, and accessibility improvements for assistive technology users.
Focus areas for Interop 2025 include CSS anchor positioning, view transitions, navigation API, backdrop-filter, JSON module scripts, and improving core web primitives.
