reveal.js is an open source HTML presentation framework that enables anyone with a web browser to create and deliver presentations.
The framework solves the problem of building presentations without proprietary software by letting developers write slides in HTML and Markdown. It works by rendering presentations in the browser, where slides can be navigated with keyboard controls, touch gestures, or an on-screen menu. The tool supports nested vertical slides for organizing content hierarchically, and includes features like Auto-Animate for smooth transitions between related slides, speaker notes for presenter reference, PDF export for offline sharing, LaTeX typesetting for mathematical notation, and syntax highlighting for code blocks.
The project suits developers and technical presenters who want full control over presentation markup and styling, or anyone comfortable writing HTML and Markdown. It works well for conference talks, technical documentation, educational content, and any presentation that benefits from version control and customization. For those preferring a graphical interface, the same team offers a visual editor at Slides.com. The framework's extensive API allows deep customization and integration into larger applications.
The project maintains active test coverage through continuous integration workflows. Development activity shows consistent engagement with the codebase through regular updates and maintenance of the core framework and its documentation.
