The document discusses using HTML hypermedia APIs and adaptive web design together. HTML hypermedia APIs use standard HTML to build APIs that follow the hypermedia constraint, where clients interact by following links and submitting forms. Adaptive web design allows a single codebase to work across different devices by responding to features and making content and layout fluid. The document argues that HTML hypermedia APIs and adaptive web design work well together by allowing the same code and templates to be used for both the web interface and API, with separate URLs and optimizations for different perspectives. A demo is shown of a kanban board application built with this approach.
