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.

-
- - Down arrow - -
-
-

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.

-
- - Up arrow - -
-
- -
-

Slides

-

- Not a coder? Not a problem. There's a fully-featured visual editor for authoring these, try it out at https://slides.com. -

-
- -
-

Hidden Slides

-

- This slide is visible in the source, but hidden when the presentation is viewed. You can show all hidden slides by setting the `showHiddenSlides` config option to `true`. -

-
- -
-

Pretty Code

- 

-						import React, { useState } from 'react';
-
-						function Example() {
-						  const [count, setCount] = useState(0);
-
-						  return (
-						    ...
-						  );
-						}
-
-

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.

- - -
- -
-

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. -
