Transition Styles

You can select from different transitions, like: Cube - Page - Concave - Zoom - Linear - Fade - None - Default

Themes

Reveal.js comes with a few themes built in: Default - Sky - Beige - Simple - Serif - Night Moon - Solarized

* Theme demos are loaded after the presentation which leads to flicker. In production you should load your theme in the <head> using a <link>.

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 background.

Custom 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' );
} );

Slide Backgrounds

Set data-background="#007777" on a slide to change the full page background to the given color. All CSS color formats are supported.

Image Backgrounds

<section data-background="image.png">

Repeated Image Backgrounds

<section data-background="image.png" data-background-repeat="repeat" data-background-size="100px">

Background Transitions

Pass reveal.js the backgroundTransition: 'slide' config argument to make backgrounds slide rather than fade.

Background Transition Override

You can override background transitions per slide by using data-background-transition="slide".

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.”

Pretty Code

function linkify( selector ) {
  if( supports3DTransforms ) {

    var nodes = document.querySelectorAll( selector );

    for( var i = 0, len = nodes.length; i < len; i++ ) {
      var node = nodes[i];

      if( !node.className ) {
        node.className += ' roll';
      }
    }
  }
}

Intergalactic Interconnections

You can link between slides internally, like this.

Fragmented Views
