Responsive Web Design (RWD) is a web design method that automatically renders the website based on the screen size (or the viewport size). As a result, regardless of the device used to visit the website, the look and feel (i.e., design, layout, and experience) should stay the same. Here in this screenshot of the LT Browser, you can see an example of responsive web design.
