Interop 2025 is gearing up with an open call for proposals, inviting developers to suggest enhancements for the web platform. Building on the successes of Interop 2024, which improved key areas like CSS nesting and anchor positioning, Microsoft Edge emphasizes the need for transparency and community involvement to prioritize essential features for a more interoperable web.2. ** in HTML:**

Interop 2025: Shaping the Future of Web Development
Microsoft has officially opened the call for proposals for Interop 2025. This initiative aims to address the pressing needs of web developers. Since its inception in 2021, the Interop project has significantly improved the web platform.
What’s New in Interop 2025?
Interop 2025 is set to expand on the successes of previous years. Developers are encouraged to submit proposals via the submission form. This collaborative effort aims to tackle the most critical pain points within the web development community.
“We need your help in identifying the right areas to focus on.”
Major Updates from Interop 2024
Earlier this year, the Interop 2024 project launched in collaboration with major players like Apple and Google. Focus areas included:
- CSS Nesting
- Font-size-adjust
- HTTPS URLs for WebSocket
- RequestVideoFrameCallback
- @starting-style & transition-behavior
These improvements are paving the way for greater interoperability across browsers.
Key Improvements to Note
Several important updates have already been implemented:
- Anchor Positioning: Now supported in Edge and other Chromium browsers, simplifying tooltip positioning.
- Document.caretPositionFromPoint(): This API enhances text editing libraries by detecting user insertion points.
- View Transitions API: Coming to Safari, it will redefine multi-page site transitions.
- Scrolling to Text Fragments: Firefox will soon support sharing URLs with highlighted text snippets.
“Now is not the time to slow down, but instead accelerate towards a highly capable and interoperable platform.”
What’s Important to Know?
The Interop project is not exhaustive. Some web platform APIs still lack universal browser support. Microsoft has published the Edge 2024 web platform top developer needs dashboard to highlight critical gaps. This dashboard aims to provide a more comprehensive view of developers’ needs.
As we look forward to Interop 2025, your input is invaluable. Whether you have a specific focus area or want to support existing proposals, your feedback will help prioritize necessary improvements. Join the conversation and contribute to the future of web development!
