The “big bang” of Web fonts in 2010 — when browsers started supporting downloadable fonts — started a revolution in Web typography.

How do type design and rendering technology interact? What do Web fonts look like inside? How do foundries optimize their fonts? What can the font user contribute to make the final result look as good as it possibly gets?
