Responsive Design refers to the ability of a website or application to respond to a user’s screen size, platform, device orientation, and behavior. The position of the primary contentwill be placed in a manner that minimizes the need for screen resizing, panning, and excessive scrolling.

Essentially, responsive design is a way to put together a website so that it automatically scales its content and elements to match the screen size on which it is viewed. It keeps images from being larger than the screen width, and prevents visitors on mobile devices from needing to do extra work to read your content.
