The web as we know and build it has primarily been accessed from the desktop. That is about to change. The ITU predicts that in the next 18–24 months, mobile devices will overtake PCs as the most popular way to access the web. If these predictions come true, very soon the web—and its users—will be mostly mobile. Even designers who embrace this change can find it confusing. One problem is that we still consider the mobile web a separate thing. Stephanie Rieger of futurefriend.ly and the W3C presents principles to understand and design for a new normal, in which users are channel agnostic, devices are plentiful, standards are fleeting, mobile use doesn’t necessarily mean “hide the desktop version,” and every byte counts.
