Responsive design is an approach to web development that ensures a website’s layout and functionality adapt seamlessly to various screen sizes and devices. It involves designing and coding in a way that allows the site to respond to the user’s environment, providing an optimal viewing experience on desktops, tablets, and smartphones.

The importance of responsive design in web development lies in the diverse ways people access the internet. With the prevalence of mobile devices, having a responsive website is crucial for reaching a broader audience and providing a consistent user experience. It eliminates the need for separate mobile and desktop sites, streamlining maintenance and improving search engine rankings. Responsive design enhances user satisfaction by delivering content in a visually appealing and accessible manner across different devices, ultimately contributing to a positive overall user experience.
