Responsive Web Design (RWD) encapsulates many different ideas and technologies, but essentially it indicates that a web site is crafted to use W3C CSS3 media queries to adapt the layout to the environment that it is being viewed in. As a result, mobile (smartphone/tablet) users will have a similar experience and see similar content to Desktop users — but the content will be laid out in such a way to ensure that the content is readable without having to zoom or do any kind of resizing. Concepts related to RWD include "Fluid grids" and "Fluid Images".
