I’ve really enjoy reading Ethan Marcotte’s book, Responsive Web Design. It’s so easy to read, and full of great info that you can put to use immediately. In fact, I’ve already started re-constructing many of my web projects so that they can be more “responsive.” As well, at work, we are talking about this a lot and we have just completed a project that is fully “responsive” (well, it’s about 80% there, I’d say – as it supports tablet and desktop perfectly, but needs some work for the mobile phone.) What’s amazing is how simple it is to make a design responsive.
