Responsive Web Design (RWD) is a type of Web Design that optimizes the navigation and viewing experience of web pages across a wide range of devices (i.e. smartphones, tablets, and computers). Websites designed with RWD will look different on a smartphone than they will on a computer screen. This is because the coding recognizes the screen resolution of each separate device and renders graphics and layout appropriately. RWD utilizes the latest technologies such as CSS3 and HTML 5 which are fast becoming the industry standard in Web Design and Development.
