Keynote. New Adventures in Front-End, Season 2
summary
755 rapid slides claim concrete wins and weird hacks: images are 5.4 MB on average with 70% images so techniques include CSS filters to strip contrast, tuned progressive JPEG scans (use adapt or guetz/goodsleep style encoders), and ML upscaling via letsenhance.io; web fonts use font-display, service worker caching and Unicode-range subsetting after noting ~44.6% empty cache hits and toolchain like responsive breakpoints generator; third‑party map + WebPageTest exposes 144 scripts on one site and enables iframe sandboxing; interactive email is built with checkbox/radio hacks (117 radios, 44 checkboxes) and it works.
