Welcome to Day Two
summary
MDN's Web DNA reports 28,000+ responses from 173 countries and pushes browser teams to focus on compatibility; Firefox DevTools adds a Compatibility panel, a Profiler with shareable links, a watchpoint breakpoint and source-map-aware scopes. Chrome and CSS landers include aspect-ratio and gap for Flexbox, the app property rule and Houdini APIs, and richer Web Animations. Chrome DevTools surfaces web vitals (FCP/LCP), an Issues tab, candy-striped long tasks, Layout Shift overlays, WebAssembly debugging, color-vision emulation, and TensorFlow.js demos (body segmentation, face‑mesh, Teachable Machine) that run locally for low-latency, privacy-preserving ML.
