The document discusses how DITA (Darwin Information Typing Architecture) content and responsive web design (RWD) can work together effectively. It provides background on Yellow Pencil, a web design agency specialized in content-first and responsive design projects. The presentation then covers key principles of RWD including fluid layouts, flexible images and navigation, and benefits such as universal access across devices. Examples are given of how DITA content structures can map to RWD frameworks to generate optimized HTML for different screen sizes.
