Font math and CSS
When I created the Body Size Comparison part of Web Font Specimen, I knew there was more to learn about the impact font files’ sizing and spacing has on CSS. Now, with the help of my talented colleagues at Typekit, the mystery unfolds.
After some serious (and seriously maddening) research, Matt Colyer and I got a better idea about how fonts are sized and spaced in CSS — and how it relates to the math within font files. We turned this into one blog post so far, called Font metrics and vertical space in CSS, with some more detail on the way in a future post. This also set the stage for some Partner Tools at Typekit, to help us work together with our foundry partners on making type the best it can be for web typesetting.
It was awesome to work with Jason and Greg on turning sketches and plans into actual, valuable pieces of Typekit’s service, and also awesome to receive advice and direction from Jeff and Ryan.
