Responsive Web Design is a relatively new technique which involves providing a number of site layouts adapted to various screen widths, and then serving those layouts accordingly thanks to the use of CSS3 Media Queries.

In non geek terms: It’s code that checks your browser size and adjusts the layout accordingly, ensuring that whether you visit the web using a widescreen iMac or a tiny mobile device, the design will be optimized to ensure you get the most out of your web viewing experience.

Visit http://lessframework.com/ for an example of how this works; just take your web browser and make it smaller by dragging it’s corner and watch the layout change based on the browser size. Pretty cool huh? Sites like CCN.com, target.com, and ESPN.com are already implementing this technology.

And what does this mean for you? Accessibility, accessibility, accessibility! Need I say more?
