👉 A website's fluid design, also known as responsive design, is an approach that ensures the layout and content adapt seamlessly to different screen sizes and resolutions. This is achieved through flexible grids, images, and CSS media queries that adjust the layout based on the device's width, height, or orientation. Fluid designs prioritize content readability and user experience across desktops, tablets, and smartphones, providing a consistent and accessible browsing experience regardless of the device being used.
