reveal.js is an open-source HTML presentation framework that enables creation of web-based slide presentations. The framework provides a modular architecture with extensive JavaScript APIs, built-in themes, plugin system, and support for Markdown, animations, and interactive elements.

reveal.js operates as a single-page application where presentations are defined using HTML <section> elements within a .reveal container, with navigation managed through a central Reveal object that coordinates multiple specialized controllers.
