Fun side note that if you're working in digital, all the various
measurements that match real-world units ("mm", "cm", "pt", etc) are
actually, by definition in the CSS spec, all anchored on the ideal pixel
definition, so have nothing to do with their traditional/real-world
counterparts (i.e. if you define something in "pt", or "mm", and then
hold a ruler against your screen, the results will vary wildly from
their real-world equivalents...)
