reveal.js

A CSS 3D slideshow tool for quickly creating good looking HTML presentations. Doesn't rely on any external libraries but highlight.js is included by default for code highlighting.

Note that this requires a browser with support for CSS 3D transforms and classList. If CSS 3D support is not detected, the presentation will degrade to less exciting 2D transitions. A classList polyfill is incuded to make this work in < iOS 5, < Safari 5.1 and IE.

Curious about how it looks in action? Check out the demo page.

Usage

Markup

Markup heirarchy needs to be <div id="reveal"> <div class="slides"> <section> where the <section> represents one slide and can be repeated indefinitely. If you place multiple <section>'s inside of another <section> they will be shown as vertical slides. For example:

<div id="reveal">
	<div class="slides"> 
		<section>Single Horizontal Slide</section>
		<section>
			<section>Vertical Slide 1</section>
			<section>Vertical Slide 2</section>
		</section>
	</div>
</div>

Configuration

At the end of your page, after <script src="js/reveal.js"></script>, you need to initialize reveal by running the following code. Note that all config values are optional.

Reveal.initialize({
	// Display controls in the bottom right corner
	controls: true,

	// Display a presentation progress bar
	progress: true,

	// If true; each slide will be pushed to the browser history
	history: true,

	// Loops the presentation, defaults to false
	loop: false,

	// Flags if mouse wheel navigation should be enabled
	mouseWheel: true,

	// Apply a 3D roll to links on hover
	rollingLinks: true,

	// UI style
	theme: 'default', // default/neon

	// Transition style
	transition: 'default' // default/cube/page/concave/linear(2d)
});

API

The Reveal class provides a minimal JavaScript API for controlling its navigation:

  • Reveal.navigateTo( indexh, indexv );
  • Reveal.navigateLeft();
  • Reveal.navigateRight();
  • Reveal.navigateUp();
  • Reveal.navigateDown();
  • Reveal.toggleOverview();

States

If you set data-state="somestate" on a slide <section>, "somestate" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.

Furthermore you can also listen to these changes in state via JavaScript:

Reveal.addEventListener( 'somestate', function() {
	// TODO: Sprinkle magic
}, false );

Slide change event

An 'slidechanged' event is fired each time the slide is changed (regardless of state). The event object holds the index values of the current slide as well as a reference to the previous and current slide HTML nodes.

Reveal.addEventListener( 'slidechanged', function( event ) {
	// event.previousSlide, event.currentSlide, event.indexh, event.indexv
} );

Fragment events

When a slide fragment is either shown or hidden reveal.js will dispatch an event.

Reveal.addEventListener( 'fragmentshown', function( event ) {
	// event.fragment = the fragment DOM element
} );
Reveal.addEventListener( 'fragmenthidden', function( event ) {
	// event.fragment = the fragment DOM element
} );

Speaker Notes

If you're interested in using speaker notes, reveal.js comes with a Node server that allows you to deliver your presentation in one browser while viewing speaker notes in another.

To include speaker notes in your presentation, simply add an <aside class="notes"> element to any slide. These notes will be hidden in the main presentation view.

To use the speaker notes server, your index.html will need to include script tags for socket.io/socket.io.js and js/slidenotes.js. If you don't want to use the speaker notes server, you can safely remove these script tags, but they are included by default.

You'll also need to install Node.js; then, install the server dependencies by running npm install.

Once Node.js and the dependencies are installed, run the following command from the root directory:
