981: Browsers Are Finally Catching Up (Interop 2026)

Interop 2026, a collaborative effort by browser vendors, aims to standardize web development features across different browsers. The initiative focuses on achieving 100% implementation and bug-free performance for specific APIs. Container style queries, which allow styling based on CSS properties, and anchor positioning, for positioning elements relative to each other, are highlighted as significant advancements. Other key areas include CSS attributes for accessing attribute values in CSS, contrast color functions, CSS zoom, custom highlight API, and improvements to dialogues and popovers. The discussion also covers JavaScript APIs like Fetch uploads and ranges, IndexedDB API changes, JSPI for WASM, media pseudo-classes, and the Navigation API, alongside investigations into JPEG-XL and accessibility testing.
