GoKawiilMozilla opens voting to shape Interop 2027's CSS priorities
Browser makers collaborating under the Interop initiative—Google, Apple, Microsoft, Mozilla, Igalia and Bocoup—are planning their 2027 focus areas, and Mozilla has launched a public ranking tool letting developers upvote the CSS features they most want standardized across browsers. A blog post highlights the author's top 10 requested features, including native CSS functions, as examples of what could gain broad support next year.
GoKawiil's interpretation of the reporting above, not reported fact.
Interop has a track record of pushing niche features, like CSS Subgrid, to near-universal browser support within about a year of being selected, so community voting could meaningfully influence which CSS capabilities become reliably usable soon. Features like custom CSS functions, currently supported only in Chrome and Edge, suggest the kind of long-requested capability that could gain cross-browser parity if prioritized through this process.
- Mozilla created a public ranking system to crowdsource priorities for Interop 2027.
- Past Interop focus areas, like CSS Subgrid, reached near-universal browser support within about a year.
- CSS functions are among the proposed features currently supported only in Chrome and Edge.
