Responsive web design is becoming increasingly popular as more people use tablets and smartphones. A responsive website automatically adjusts the layout, image sizes, and text based on the device it is being viewed on, whether it is a desktop, laptop, tablet, or mobile phone. This allows a single website to be easily viewed and functional on any device. Some benefits of responsive design include reaching a wider audience, providing a consistent user experience across devices, improving search engine optimization as only one website needs to be optimized, and reducing costs as only one website needs to be managed and maintained.
