For a web application, detailed interaction documentation is crucial, so we'll provide comprehensive specifications that detail exactly how each element behaves. This includes state changes (hover, active, disabled, error, etc.), transition animations with timing and easing functions, micro-interactions that provide feedback to users, and pagination behaviors. We'll document how modals appear and disappear, how navigation elements transform across breakpoints, form validation behaviors, and data loading indicators. These specifications ensure developers understand not just how screens look statically, but how the entire application feels dynamically as users interact with it.
