Interop '26

Interop ’26

1 Min Read

All the major browser makers, along with Igalia, a key contributor, have released announcements for Interop 2026. I’ll refer to Apple’s announcement because I appreciate their use of column-width for the feature list, which I’m adopting here as well.

– 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 enthusiastic about all these features, particularly the new CSS enhancements. CSS shape() is particularly enjoyable. Among the less prominent features, I resonate with Jake’s sentiment:

“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.”
