Device-Agnostic (Trent Walton)

The more I build for the web, the more the term ‘device-agnostic’ endears itself to me. I used to think it merely dealt with basing responsive breakpoints on content rather than particular devices, but there’s more to devices than the size of their screens. A device-agnostic approach also takes into account infinite combinations of screen resolution, input method, browser capability, and connection speed. (trentwalton.com)
