It is very important to have a responsive website as no user will prefer to invest his/her time to open a system just for browsing a website. A responsive site plays a major role in improving the usability of the product. A normal website, when viewed on small devices, looks like a replica of the actual site and it would be difficult to read or use. A responsive site responds or adapts depending upon the layout of the device providing the best user experience regardless of what device is being used. HTML and CSS are used for responsive website design for having a good viewing experience. Normal websites are not really user-friendly and it just serves the purpose of having a web presence. The problem with a normal website is that it does not respond well to the users when accessed from a mobile or other small devices. It is essential to make a responsive website optimized for mobile as Google is now prioritizing mobile-friendly websites in its search results algorithm. There are chances of losing page ranking for your website if it is not built with responsive web design. Building a responsive site is a right decision to find new customers. Sometimes while using a normal website the users find it frustrating or difficult to pinch or zoom in order to read the contents and are likely to abandon the site whereas a responsive site is a unified site and it has the flexibility to adapt automatically making it user-friendly.
