In today’s world, the internet is one of the most important forms of media. In the past the internet was mostly accessed by desktop computers but usage by mobile devices such as smart phones and tablets has increased exponentially. This means that if you don’t want to lose customers, your site needs to be optimized for mobile devices as well as desktop computers. That’s where responsive design comes in. Instead of creating multiple versions of one site for different devices, responsive websites will re-arrange elements to fit any screen or device. That leads to happy visitors and happy customers.
