A responsive website is a website that “responds” to the container or device it is displaying on. What that means is that your website shrinks and expands to display correctly in a smartphone just as well as a tablet or desktop. The beauty of this is that your brand stays consistent and consumers can identify your website on whichever device they are on.
Responsive websites became very popular a couple years ago in large part due to their ability to conform to individual devices and the fact that no design element would be lost in translation. However, the responsive website does have its limitations.And thus, Mobile design was born.
