Responsive web design is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes. This ensures that users have a good experience regardless of the device they use to access the website. Responsive web design uses flexible layouts and grids, along with images and CSS media queries, to adjust the website's design and content based on the screen size and orientation of the device.
