Responsive Design

A web design approach in which layouts, images, and other content elements adapt fluidly to the size and capabilities of the user's device, providing an optimal viewing experience across desktops, tablets, and mobile phones without requiring separate versions of a site. Responsive design uses techniques such as fluid grids, flexible images, and CSS media queries to adjust presentation. In accessibility contexts, responsive design principles can be applied beyond page layout — for example, to dynamically reformat subtitles based on screen size and user font preferences, or to ensure that interactive elements remain usable at different zoom levels and viewport sizes.
