For centuries, typography has shaped the way we ‘hear’ what we read. In our web work, though, we’ve had to balance our typographic desires with user experience and performance, knowing that every weight, width, or style of a typeface required a different file download.

In a detail-packed talk, Jason will show you not just how far the new capabilities can take us, but how to make use of them right away.
