Responsive Design

Responsive design is an development approach whereby the design of websites and software applications automatically resizes itself based on the size and type of device it is being view on.

For instance, developers can develop a website with a single design that automatically adjusts by moving elements around and changing font sizes so that it appears user friendly on phones, tablets, small screen laptops or large desktops.

These days with more and more people accessing technology from smartphones plus Google's "Mobile-First" SEO ranking system, having a website or software application that is responsive isn't just a nice to have but a clear necessity.
