reveal.js

A framework for easily creating beautiful presentations using HTML. Check out the live demo.

reveal.js comes with a broad range of features including nested slides, markdown contents, PDF export, speaker notes and a JavaScript API. It's best viewed in a browser with support for CSS 3D transforms but fallbacks are available to make sure your presentation can still be viewed elsewhere.

Online Editor

Presentations are written using HTML or markdown but there's also an online editor for those of you who prefer a graphical interface. Give it a try at http://slid.es.

Instructions

Markup

Markup hierarchy needs to be <div class="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. The first of the vertical slides is the "root" of the others (at the top), and it will be included in the horizontal sequence. For example:

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

Markdown

It's possible to write your slides using Markdown. To enable Markdown, add the data-markdown attribute to your <section> elements and wrap the contents in a <script type="text/template"> like the example below.

This is based on data-markdown from Paul Irish modified to use marked to support Github Flavoured Markdown. Sensitive to indentation (avoid mixing tabs and spaces) and line breaks (avoid consecutive breaks).

<section data-markdown>
	<script type="text/template">
		## Page title

		A paragraph with some text and a [link](http://hakim.se).
	</script>
</section>

External Markdown

You can write your content as a separate file and have reveal.js load it at runtime. Note the separator arguments which determine how slides are delimited in the external file. The data-charset attribute is optional and specifies which charset to use when loading the external file.

<section data-markdown="example.md" data-separator="^\n\n\n" data-vertical="^\n\n" data-notes="^Note:" data-charset="iso-8859-15"></section>

Element Attributes

Special syntax (in html comment) is available for adding attributes to Markdown elements. This is useful for fragments, amongst other things.

<section data-markdown>
	<script type="text/template">
		- Item 1 <!-- .element: class="fragment" data-fragment-index="2" -->
		- Item 2 <!-- .element: class="fragment" data-fragment-index="1" -->
	</script>
</section>

Slide Attributes

Special syntax (in html comment) is available for adding attributes to the slide <section> elements generated by your Markdown.

<section data-markdown>
	<script type="text/template">
	<!-- .slide: data-background="#ff0000" -->
		Mardown content
	</script>
</section>

Configuration

At the end of your page you need to initialize reveal by running the following code. Note that all config values are optional and will default as specified below.

Reveal.initialize({

	// Display controls in the bottom right corner
	controls: true,

	// Display a presentation progress bar
	progress: true,

	// Display the page number of the current slide
	slideNumber: false,

	// Push each slide change to the browser history
	history: false,

	// Enable keyboard shortcuts for navigation
	keyboard: true,

	// Enable the slide overview mode
	overview: true,

	// Vertical centering of slides
	center: true,

	// Enables touch navigation on devices with touch input
	touch: true,

	// Loop the presentation
	loop: false,

	// Change the presentation direction to be RTL
	rtl: false,

	// Turns fragments on and off globally
	fragments: true,

	// Flags if the presentation is running in an embedded mode,
	// i.e. contained within a limited portion of the screen
	embedded: false,

	// Number of milliseconds between automatically proceeding to the
	// next slide, disabled when set to 0, this value can be overwritten
	// by using a data-autoslide attribute on your slides
	autoSlide: 0,

	// Stop auto-sliding after user input
	autoSlideStoppable: true,

	// Enable slide navigation via mouse wheel
	mouseWheel: false,

	// Hides the address bar on mobile devices
	hideAddressBar: true,

	// Opens links in an iframe preview overlay
	previewLinks: false,

	// Transition style
	transition: 'default', // default/cube/page/concave/zoom/linear/fade/none

	// Transition speed
	transitionSpeed: 'default', // default/fast/slow

	// Transition style for full page slide backgrounds
	backgroundTransition: 'default', // default/none/slide/concave/convex/zoom

	// Number of slides away from the current that are visible
	viewDistance: 3,

	// Parallax background image
	parallaxBackgroundImage: '', // e.g. "'https://s3.amazonaws.com/hakim-static/reveal-js/reveal-parallax-1.jpg'"

	// Parallax background size
	parallaxBackgroundSize: '' // CSS syntax, e.g. "2100px 900px"


});

Note that the new default vertical centering option will break compatibility with slides that were using transitions with backgrounds (cube and page). To restore the previous behavior, set center to false.

The configuration can be updated after initialization using the configure method:

// Turn autoSlide off
Reveal.configure({ autoSlide: 0 });

// Start auto-sliding every 5s
Reveal.configure({ autoSlide: 5000 });
