Responsive web design (RWD) is an approach to web design that adjusts the layout of your website according to which device it is being viewed on, all in order to provide an optimal viewing experience. No matter which device a user uses to access the web, with RWD your website will preserve its quality. Whether you are viewing the site on a desktop, an iPhone or an iPad, your site will adjust to all types of screens – big screens, tablets and smartphones. The days of pinching screens to zoom in and out are long gone.
