What is it?

reveal.js is an HTML presentation framework. Slides are written as HTML, so any web browser can display them, and the project is aimed at anyone who wants to build presentations without a desktop slide editor.

The framework supports nested (vertical) slides, Markdown-authored slides, Auto-Animate transitions, PDF export, speaker notes, LaTeX math, syntax-highlighted code blocks, and an extensive JavaScript API for controlling the presentation.
