The HTML presentation framework | reveal.js
Documentation and demos for the open source reveal.js HTML presentation framework.
Categories:
reveal.js is an open-source HTML presentation framework that enables anyone with a web browser to create fully-featured, beautiful, and interactive slide decks using standard web technologies.
🚀 Overview
reveal.js is a powerful, flexible framework for building presentations entirely with HTML, CSS, and JavaScript. It turns any modern web browser into a presentation powerhouse, supporting everything from simple slides to complex, interactive experiences with nested content, animations, and embeds.
This project solves the limitations of proprietary tools like PowerPoint or Keynote, which lock users into closed ecosystems, restrict creativity, and require paid software. With reveal.js, presentations are free, portable, version-controlled, and infinitely customizable using open web standards—no installations needed.
It's built for web developers, educators, conference speakers, and anyone who wants professional-grade presentations without barriers. Hakim El Hattab created it in 2011 to demonstrate the potential of HTML5 for storytelling and has since grown it into a beloved tool used by millions.
