W3C Candidate Recommendation 27 July 2010

@Media Queries (http://www.w3.org/TR/css3-mediaqueries) are going to be the ultimate tool in the web designers toolbox for many years to come. That is why we should brush up on the devices we will be targeting in this age of mobile freedom.

Basically, this means you can change stylesheets based on for instance the width and height of the viewport. In a broader sense, this means as the spec puts it: “by using Media Queries, presentations can be tailored to a specific range of output devices without changing the content itself.”

Even though we use the term "mobile", let's not confuse this term with the idea of "small screens." Mobile means something entirely different and more complex, but first let us look at the devices we will be targeting in our queries.
