Web Typography

Nothing fancy here. I just built a little typography system for a project at work. I used a weird combination of Apple's iOS typography guidelines mixed with some values from gridlover.net. I use a 6px base grid and a 12px baseline grid. I want my vertical values to add up to values of 6. Apple's don't. I also used Roboto instead of SF Display. I think it turned out well.
