We’ve barely scratched the surface of typography on the web — and the reason why will shock you to your core. (Just kidding about that last bit). The web is so different to print, yet we’re stuck in the ways of designing around our knowledge of previous media. We need better tools to experiment, design, and build out typography that is native to the web medium. Now’s the time for us to start to push forwards with the future of typography on the web, and to forge its own language and best practices.
