Media queries blah blah blah. You've all heard that talk a hundred times, so I won't do that. Instead, I'll go beyond the obvious, looking at what we can do today to adapt our front-ends to different browsing environments, from mobiles and other alternative devices to older browsers we may be called upon to support.
You'll learn advanced media query and viewport tricks, including a look at @viewport, Insights into responsive images: problems, and current solutions, providing usable alternatives to older browsers with Modernizr and YepNope, other CSS3 responsive goodness - multi-col, Flexbox, and more, and finally where RWD is going ‚Äî matchMedia, CSS4 media queries, etc.
Clipping is a handy way to collect important slides you want to go back to later.
