Less, and the right less
Dieter Rams

Typography
Most of an interface is text. Its quality is decided by the same few things as a book: a typeface made for reading, a measure that does not tire the eye, and an order that is clear before a word is read. This site is set in Fira Sans and Source Serif 4, on a single axis, for that reason. See specimen.
