Documentation and demos for the open source reveal.js HTML presentation framework.

The HTML Presentation Framework
Created by Hakim El Hattab and contributors
Hello There
reveal.js enables you to create beautiful interactive slide decks using HTML. This presentation will show you examples of what it can do.
Vertical Slides
Slides can be nested inside of each other.
Use the Space key to navigate through all slides.
Basement Level 1
Nested slides are useful for adding additional detail underneath a high level horizontal slide.
Basement Level 2
That’s it, time to go back up.
Slides
Not a coder? Not a problem. There’s a fully-featured visual editor for authoring these, try it out at https://slides.com.
Pretty Code
import React, { useState } from ‘react’;
function Example() {
const [count, setCount] = useState(0);
return (
…
);
}
Code syntax highlighting courtesy of highlight.js.
Even Prettier Animations
import React, { useState } from ‘react’;
function Example() {
const [count, setCount] = useState(0);
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>
Click me
</button>
</div>
);
}
function SecondExample() {
const [count, setCount] = useState(0);
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>
Click me
</button>
</div>
);
}

Transition Styles
You can select from different transitions, like:None – Fade – Slide – Convex – Concave – Zoom
Slide Backgrounds
Set data-background=”#dddddd” on a slide to change the background color. All CSS color formats are supported.
Image Backgrounds
<section data-background=”image.png”>
Tiled Backgrounds
<section data-background=”image.png” data-background-repeat=”repeat” data-background-size=”100px”>
Video Backgrounds
<section data-background-video=”video.mp4,video.webm”>
… and GIFs!
Background Transitions
Different background transitions are available via the backgroundTransition option. This one’s called “zoom”.
Reveal.configure({ backgroundTransition: ‘zoom’ })
Background Transitions
You can override background transitions per-slide.
<section data-background-transition=”zoom”>
Iframe Backgrounds
Since reveal.js runs on the web, you can easily embed other web content. Try interacting with the page in the background.

Clever Quotes
These guys come in two forms, inline: The nice thing about standards is that there are so many to choose from and block:
“For years there has been a theory that millions of monkeys typing at random on millions of typewriters would reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.”
Intergalactic Interconnections
You can link between slides internally, like this.
Speaker View
There’s a speaker view. It includes a timer, preview of the upcoming slide as well as your speaker notes.
Press the S key to try it out.
Oh hey, these are some notes. They’ll be hidden in your presentation, but you can see them if you open the speaker notes window (hit ‘s’ on your keyboard).
Export to PDF
Presentations can be exported to PDF, here’s an example:
Global State
Set data-state=”something” on a slide and “something” will be added as a class to the document element when the slide is open. This lets you apply broader style changes, like switching the page background.
State Events
Additionally custom events can be triggered on a per slide basis by binding to the data-state name.
Reveal.on( ‘customevent’, function() {
console.log( ‘”customevent” has fired’ );
} );
Take a Moment
Press B or . on your keyboard to pause the presentation. This is helpful when you’re on stage and want to take distracting slides off the screen.
