Implementing Responsive Design 2012

Book Description
New devices and platforms emerge daily. Browsers iterate at a remarkable pace. Faced with this volatile landscape we can either struggle for control or we can embrace the inherent flexibility of the web.
Responsive design is not just another technique–it is the beginning of the maturation of a medium and a fundamental shift in the way we think about the web.
Implementing Responsive Design is a discussion about how this affects the way we design, build, and think about our sites. Readers will learn how to:

Build responsive sites using a combination of fluid layouts, media queries and fluid media
Adopt a responsive workflow from the very start of a project
Enhance content for different devices
Use feature-detection and server-side enhancement to provide a richer experience
