This is a prototype corporate deck template built by Minds that you are free to contribute to or fork. You can see a demo in chrome at https://connorlee.github.io/MindsHTML/#/
Here's a barebones example of the presentation:
The presentation markup hierarchy needs to be .reveal > .slides > section where the section represents one slide and can be repeated indefinitely. If you place multiple section elements 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 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>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>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>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" -->
Markdown content
</script>
</section>See below for a list of configuration options related to sizing, including default values:
Reveal.initialize({
...
// The "normal" size of the presentation, aspect ratio will be preserved
// when the presentation is scaled to fit different resolutions. Can be
// specified using percentage units.
width: 960,
height: 700,
// Factor of the display size that should remain empty around the content
margin: 0.1,
// Bounds for smallest/largest possible scale to apply to content
minScale: 0.2,
maxScale: 1.5
});These libraries are loaded as dependencies in the order they appear:
Reveal.initialize({
dependencies: [
// Cross-browser shim that fully implements classList - https://github.com/eligrey/classList.js/
{ src: 'lib/js/classList.js', condition: function() { return !document.body.classList; } },
// Interpret Markdown in <section> elements
{ src: 'plugin/markdown/marked.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
{ src: 'plugin/markdown/markdown.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },
// Syntax highlight for <code> elements
{ src: 'plugin/highlight/highlight.js', async: true, callback: function() { hljs.initHighlightingOnLoad(); } },
// Zoom in and out with Alt+click
{ src: 'plugin/zoom-js/zoom.js', async: true },
// Speaker notes
{ src: 'plugin/notes/notes.js', async: true },
// MathJax
{ src: 'plugin/math/math.js', async: true }
]
});You can add your own extensions using the same syntax. The following properties are available for each dependency object:
- src: Path to the script to load
- async: [optional] Flags if the script should load after reveal.js has started, defaults to false
- callback: [optional] Function to execute when the script has loaded
- condition: [optional] Function which must return true for the script to be loaded
Reveal.addEventListener( 'ready', function( event ) {
// event.currentSlide, event.indexh, event.indexv
} );Presentations can be configured to progress through slides automatically, without any user input. To enable this you will need to tell the framework how many milliseconds it should wait between slides:
// Slide every five seconds
Reveal.configure({
autoSlide: 5000
});When this is turned on a control element will appear that enables users to pause and resume auto-sliding. Alternatively, sliding can be paused or resumed by pressing »a« on the keyboard. Sliding is paused automatically as soon as the user starts navigating. You can disable these controls by specifying autoSlideStoppable: false in your reveal.js config.
You can also override the slide duration for individual slides and fragments by using the data-autoslide attribute:
<section data-autoslide="2000">
<p>After 2 seconds the first fragment will be shown.</p>
<p class="fragment" data-autoslide="10000">After 10 seconds the next fragment will be shown.</p>
<p class="fragment">Now, the fragment is displayed for 2 seconds before the next slide is shown.</p>
</section>Whenever the auto-slide mode is resumed or paused the autoslideresumed and autoslidepaused events are fired.
If you're unhappy with any of the default keyboard bindings you can override them using the keyboard config option:
Reveal.configure({
keyboard: {
13: 'next', // go to the next slide when the ENTER key is pressed
27: function() {}, // do something custom when ESC is pressed
32: null // don't do anything when SPACE is pressed (i.e. disable a reveal.js default binding)
}
});You can swipe to navigate through a presentation on any touch-enabled device. Horizontal swipes change between horizontal slides, vertical swipes change between vertical slides. If you wish to disable this you can set the touch config option to false when initializing reveal.js.
If there's some part of your content that needs to remain accessible to touch events you'll need to highlight this by adding a data-prevent-swipe attribute to the element. One common example where this is useful is elements that need to be scrolled.
When working on presentation with a lot of media or iframe content it's important to load lazily. Lazy loading means that reveal.js will only load content for the few slides nearest to the current slide. The number of slides that are preloaded is determined by the viewDistance configuration option.
To enable lazy loading all you need to do is change your "src" attributes to "data-src" as shown below. This is supported for image, video, audio and iframe elements. Lazy loaded iframes will also unload when the containing slide is no longer visible.
<section>
<img data-src="image.png">
<iframe data-src="http://hakim.se"></iframe>
<video>
<source data-src="video.webm" type="video/webm" />
<source data-src="video.mp4" type="video/mp4" />
</video>
</section>A 'slidechanged' event is fired each time the slide is changed (regardless of state). The event object holds the index values of the current slide as well as a reference to the previous and current slide HTML nodes.
Some libraries, like MathJax (see #226), get confused by the transforms and display states of slides. Often times, this can be fixed by calling their update or render function from this callback.
Reveal.addEventListener( 'slidechanged', function( event ) {
// event.previousSlide, event.currentSlide, event.indexh, event.indexv
} );The presentation's current state can be fetched by using the getState method. A state object contains all of the information required to put the presentation back as it was when getState was first called. Sort of like a snapshot. It's a simple object that can easily be stringified and persisted or sent over the wire.
Reveal.slide( 1 );
// we're on slide 1
var state = Reveal.getState();
Reveal.slide( 3 );
// we're on slide 3
Reveal.setState( state );
// we're back on slide 1If you set data-state="somestate" on a slide <section>, "somestate" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.
Furthermore you can also listen to these changes in state via JavaScript:
Reveal.addEventListener( 'somestate', function() {
// TODO: Sprinkle magic
}, false );Slides are contained within a limited portion of the screen by default to allow them to fit any display and scale uniformly. You can apply full page backgrounds outside of the slide area by adding a data-background attribute to your <section> elements. Four different types of backgrounds are supported: color, image, video and iframe. Below are a few examples.
<section data-background="#ff0000">
<h2>All CSS color formats are supported, like rgba() or hsl().</h2>
</section>
<section data-background="http://example.com/image.png">
<h2>This slide will have a full-size background image.</h2>
</section>
<section data-background="http://example.com/image.png" data-background-size="100px" data-background-repeat="repeat">
<h2>This background image will be sized to 100px and repeated.</h2>
</section>
<section data-background-video="https://s3.amazonaws.com/static.slid.es/site/homepage/v1/homepage-video-editor.mp4,https://s3.amazonaws.com/static.slid.es/site/homepage/v1/homepage-video-editor.webm" data-background-video-loop>
<h2>Video. Multiple sources can be defined using a comma separated list. Video will loop when the data-background-video-loop attribute is provided.</h2>
</section>
<section data-background-iframe="https://slides.com">
<h2>Embeds a web page as a background. Note that the page won't be interactive.</h2>
</section>Backgrounds transition using a fade animation by default. This can be changed to a linear sliding transition by passing backgroundTransition: 'slide' to the Reveal.initialize() call. Alternatively you can set data-background-transition on any section with a background to override that specific transition.
If you want to use a parallax scrolling background, set the first two config properties below when initializing reveal.js (the other two are optional).
Reveal.initialize({
// 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" - currently only pixels are supported (don't use % or auto)
// Number of pixels to move the parallax background per slide
// - Calculated automatically unless specified
// - Set to 0 to disable movement along an axis
parallaxBackgroundHorizontal: 200,
parallaxBackgroundVertical: 50
});Make sure that the background size is much bigger than screen size to allow for some scrolling. View example.
The global presentation transition is set using the transition config value. You can override the global transition for a specific slide by using the data-transition attribute:
<section data-transition="zoom">
<h2>This slide will override the presentation transition and zoom!</h2>
</section>
<section data-transition-speed="fast">
<h2>Choose from three transition speeds: default, fast or slow!</h2>
</section>You can also use different in and out transitions for the same slide:
<section data-transition="slide">
The train goes on …
</section>
<section data-transition="slide">
and on …
</section>
<section data-transition="slide-in fade-out">
and stops.
</section>
<section data-transition="fade-in slide-out">
(Passengers entering and leaving)
</section>
<section data-transition="slide">
And it starts again.
</section>It's easy to link between slides. The first example below targets the index of another slide whereas the second targets a slide with an ID attribute (<section id="some-slide">):
<a href="#/2/2">Link</a>
<a href="#/some-slide">Link</a>You can also add relative navigation links, similar to the built in reveal.js controls, by appending one of the following classes on any element. Note that each element is automatically given an enabled class when it's a valid navigation route based on the current slide.
<a href="#" class="navigate-left">
<a href="#" class="navigate-right">
<a href="#" class="navigate-up">
<a href="#" class="navigate-down">
<a href="#" class="navigate-prev"> <!-- Previous vertical or horizontal slide -->
<a href="#" class="navigate-next"> <!-- Next vertical or horizontal slide -->Fragments are used to highlight individual elements on a slide. Every element with the class fragment will be stepped through before moving on to the next slide. Here's an example: http://lab.hakim.se/reveal-js/#/fragments
The default fragment style is to start out invisible and fade in. This style can be changed by appending a different class to the fragment:
<section>
<p class="fragment grow">grow</p>
<p class="fragment shrink">shrink</p>
<p class="fragment fade-out">fade-out</p>
<p class="fragment current-visible">visible only once</p>
<p class="fragment highlight-current-blue">blue only once</p>
<p class="fragment highlight-red">highlight-red</p>
<p class="fragment highlight-green">highlight-green</p>
<p class="fragment highlight-blue">highlight-blue</p>
</section>Multiple fragments can be applied to the same element sequentially by wrapping it, this will fade in the text on the first step and fade it back out on the second.
<section>
<span class="fragment fade-in">
<span class="fragment fade-out">I'll fade in, then out</span>
</span>
</section>The display order of fragments can be controlled using the data-fragment-index attribute.
<section>
<p class="fragment" data-fragment-index="3">Appears last</p>
<p class="fragment" data-fragment-index="1">Appears first</p>
<p class="fragment" data-fragment-index="2">Appears second</p>
