All the big browser makers (and Igalia, a major contributor) dropped their timed blog posts announcing Interop 2026. I’ll link to Apple’s because I like how they used column-width on the feature list and I’m stealing that (in case you see this post directly).
- Anchor Positioning
- Advanced
attr() - Container Style Queries
contrast-color()- Custom Highlights
- Dialog and popover additions
- Fetch Uploads and Ranges
getAllRecords()for IndexedDB- JSPI for Wasm
- Media pseudo-classes
- Navigation API
- Scoped Custom Element Registries
- Scroll-driven Animations
- Scroll Snap
shape()- View Transitions
- Web Compat
- WebRTC
- WebTransport
- CSS Zoom
I’m a fan of all of it but of course I’m extra happy for the newfangled CSS stuff. CSS shape() is just… fun. But of the less-flashy features on the list, I like how Jake says:
Again, these are less headline-grabbing than the shiny new features, but it’s these edge cases where us web developers lose hours of our time. Frustrating, frustrating, hours.
