Modern Typographic Systems With Variable Fonts
summary
Variable fonts plus CSS custom properties and calc actually let typography scale fluidly by size, weight, width and grade rather than by extra files, with concrete wins: 84k replaces 18 files and IBM’s variable Plex turns ~960k across 16 files into two files at 233k. Dev tools expose axes live so values are copy‑able, a progressive font enrichment demo serves 6.5k instead of 21k for a page, and a Georgia design system runs this in production across ~80–100 sites.
