# Reveal.js

### 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.

## Point of View

Press ESC to enter the slide overview.

Hold down the alt key (ctrl in Linux) and click on any element to zoom towards it using zoom.js. Click again to zoom back out.

(NOTE: Use ctrl + click in Linux.)

## Touch Optimized

Presentations look great on touch devices, like mobile phones and tablets. Simply swipe through your slides.

## Fragments

Hit the next arrow...

... to step through ...

... a fragmented slide.

This slide has fragments which are also stepped through in the notes window.

## Fragment Styles

There's different types of fragments, like:

grow

shrink

fade-out

fade-right, up, down, left

fade-in-then-out

fade-in-then-semi-out

Highlight red blue green

## Transition Styles

You can select from different transitions, like:
None - Fade - Slide - Convex - Concave - Zoom

## Themes

reveal.js comes with a few themes built in:
Black (default) - White - League - Sky - Beige - Simple
Serif - Blood - Night - Moon - Solarized

## 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.

## Pretty Code

    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>
      );
    }

## Marvelous List

- No order here
- Or here
- Or here
- Or here

## Fantastic Ordered List

1. One is smaller than...
2. Two is smaller than...
3. Three!

## Tabular Tables

Item | Value | Quantity
--- | --- | ---
Apples | $1 | 7
Lemonade | $2 | 18
Bread | $3 | 2

## 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.addEventListener( '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.
