Building on the principles of responsive web design first codified by Ethan Marcotte, a revolution in email design is giving birth to an experience fast approaching that of the modern web. Subscribers need no longer be subjected to terrible reading experiences, frustrating touch targets, and tiny text.

As reported by Cameron McCormack, Firefox Nightly (version 29) now supports CSS variables. You can get a quick overview in this short screencast:

The Encrypted Media Extensions (DRM in HTML5) specification does not solve the problem the authors are attempting to solve, which is the protection of content from opportunistic or professional piracy. The HTML WG should not publish First Public Working Drafts that do not effectively address the primary goal of a specification.

Responsive web design is the practice of building a website suitable to work on every device and every screen size, no matter how large or small, mobile or desktop. Responsive web design is focused around providing an intuitive and gratifying experience for everyone. Desktop computer and cell phone users alike all benefit from responsive websites.

The information is pretty much just a copy of what is found in the WHATWG specs, just condensed and hopefully a bit easier to read. There are virtually no explanations, however, and no examples other than some graphics for compositing values and a few other things (the appearance of which is very much inspired by those found in Mozilla's examples).
