This document discusses responsive web design (RWD), which allows websites to adapt to different screen sizes and devices. RWD involves building flexible layouts with grids, images, and media queries so a site can work on any device without needing separate mobile or desktop versions. Content is key in RWD - it must be structured, fluid, and consistent across devices. Common challenges include images, videos, navigation, and third-party content on different screens. Examples of RWD in higher education are provided.
