What is responsive web design?

Responsive web design is a style of web development where both the layout and the content responds to the device on which it is being rendered and the size of the screen it is presented on. If you’re viewing this article on a desktop browser, for example, try resizing your browser window. The content will adjust accordingly to best fit the window size.

Why is responsive design vital?

Responsive web design is not only about adjustable screens and automatically resizable images, but rather about a whole new approach to web design. Given the fact that the amount of tablets and smartphone users is unprecedented, web designers and developers want to eliminate the need for a different design and development phase for each new device. The solution is to build one site that has the ability to adapt to all devices.
