Web design is constantly changing. Every year or so new technology is developed making the previous technology obsolete. Currently, the importance of responsive web design cannot be understated. Within the next few years experts are expecting mobile browsing to outpace the a typical desktop browsing. New video consoles now include high-end web browsers. Essentially, you don’t need a computer to surf the web anymore, and in a couple of years there is a very good possibility that no one will.
Therefore the importance of constructing web sites to be accessible across every web browser is increasing every passing day. Who knows, maybe within the next few years’ computers will be obsolete.
