I’ve created a presentation about responsive web design (mostly about processes and key points which need to be taken into account).
Best viewed using keynote. Please check presenter notes for more information about the slides.
Recommended sources, tools, books:
Luke Wroblewski – Mobile First
Ethan Marcotte – Responsive Web Design
Both from 2010, but they give a nice overview.
Aaron Gustafson – Adaptive Web Design: Crafting Rich Experiences with Progressive Enhancement (2011)
Tim Kadlec – Implementing Responsive design (2013)
This goes into technical details..
