[Check out the live demo](http://lab.hakim.se/reveal-js/).\n\nreveal.js comes with a broad range of features including [nested slides](https://github.com/hakimel/reveal.js#markup), [Markdown contents](https://github.com/hakimel/reveal.js#markdown), [PDF export](https://github.com/hakimel/reveal.js#pdf-export), [speaker notes](https://github.com/hakimel/reveal.js#speaker-notes) and a [JavaScript API](https://github.com/hakimel/reveal.js#api). It's best viewed in a modern browser but [fallbacks](https://github.com/hakimel/reveal.js/wiki/Browser-Support) are available to make sure your presentation can still be viewed elsewhere.\n\n\n#### More reading:\n- [Installation](#installation): Step-by-step instructions for getting reveal.js running on your computer.\n- [Changelog](https://github.com/hakimel/reveal.js/releases): Up-to-date version history.\n- [Examples](https://github.com/hakimel/reveal.js/wiki/Example-Presentations): Presentations created with reveal.js, add your own!\n- [Browser Support](https://github.com/hakimel/reveal.js/wiki/Browser-Support): Explanation of browser support and fallbacks.\n- [Plugins](https://github.com/hakimel/reveal.js/wiki/Plugins,-Tools-and-Hardware): A list of plugins that can be used to extend reveal.js.\n\n## Online Editor\n\nPresentations are written using HTML or Markdown but there's also an online editor for those of you who prefer a graphical interface. Give it a try at [http://slides.com](http://slides.com).\n\n\n## Instructions\n\n### Markup\n\nMarkup hierarchy needs to be ``

`` where the ``

`` represents one slide and can be repeated indefinitely. If you place multiple ``

``'s inside of another ``

`` they will be shown as vertical slides. The first of the vertical slides is the \"root\" of the others (at the top), and it will be included in the horizontal sequence. For example:\n\n```html\n

\n\t

\n\t\t

Single Horizontal Slide

\n\t\t

\n\t\t\t

Vertical Slide 1

\n\t\t\t

Vertical Slide 2

\n\t\t

\n\t

\n```\n\n### Markdown\n\nIt's possible to write your slides using Markdown. To enable Markdown, add the ```data-markdown``` attribute to your ```

``` elements and wrap the contents in a ```\n

\n```\n\n#### External Markdown\n\nYou can write your content as a separate file and have reveal.js load it at runtime. Note the separator arguments which determine how slides are delimited in the external file. The ```data-charset``` attribute is optional and specifies which charset to use when loading the external file.\n\nWhen used locally, this feature requires that reveal.js [runs from a local web server](#full-setup).\n\n```html\n

\n```\n\n#### Element Attributes\n\nSpecial syntax (in html comment) is available for adding attributes to Markdown elements. This is useful for fragments, amongst other things.\n\n```html\n

\n\t\n

\n```\n\n#### Slide Attributes\n\nSpecial syntax (in html comment) is available for adding attributes to the slide `

` elements generated by your Markdown.\n\n```html\n

\n\t\n

\n```\n\n\n### Configuration\n\nAt the end of your page you need to initialize reveal by running the following code. Note that all config values are optional and will default as specified below.\n\n```javascript\nReveal.initialize({\n\n\t// Display controls in the bottom right corner\n\tcontrols: true,\n\n\t// Display a presentation progress bar\n\tprogress: true,\n\n\t// Display the page number of the current slide\n\tslideNumber: false,\n\n\t// Push each slide change to the browser history\n\thistory: false,\n\n\t// Enable keyboard shortcuts for navigation\n\tkeyboard: true,\n\n\t// Enable the slide overview mode\n\toverview: true,\n\n\t// Vertical centering of slides\n\tcenter: true,\n\n\t// Enables touch navigation on devices with touch input\n\ttouch: true,\n\n\t// Loop the presentation\n\tloop: false,\n\n\t// Change the presentation direction to be RTL\n\trtl: false,\n\n\t// Turns fragments on and off globally\n\tfragments: true,\n\n\t// Flags if the presentation is running in an embedded mode,\n\t// i.e. contained within a limited portion of the screen\n\tembedded: false,\n\n\t// Flags if we should show a help overlay when the questionmark\n\t// key is pressed\n\thelp: true,\n\n\t// Number of milliseconds between automatically proceeding to the\n\t// next slide, disabled when set to 0, this value can be overwritten\n\t// by using a data-autoslide attribute on your slides\n\tautoSlide: 0,\n\n\t// Stop auto-sliding after user input\n\tautoSlideStoppable: true,\n\n\t// Enable slide navigation via mouse wheel\n\tmouseWheel: false,\n\n\t// Hides the address bar on mobile devices\n\thideAddressBar: true,\n\n\t// Opens links in an iframe preview overlay\n\tpreviewLinks: false,\n\n\t// Transition style\n\ttransition: 'default', // none/fade/slide/convex/concave/zoom\n\n\t// Transition speed\n\ttransitionSpeed: 'default', // default/fast/slow\n\n\t// Transition style for full page slide backgrounds\n\tbackgroundTransition: 'default', // none/fade/slide/convex/concave/zoom\n\n\t// Number of slides away from the current that are visible\n\tviewDistance: 3,\n\n\t// Parallax background image\n\tparallaxBackgroundImage: '', // e.g. \"'https://s3.amazonaws.com/hakim-static/reveal-js/reveal-parallax-1.jpg'\"\n\n\t// Parallax background size\n\tparallaxBackgroundSize: '' // CSS syntax, e.g. \"2100px 900px\"\n\n\t// Amount to move parallax background (horizontal and vertical) on slide change\n\t// Number, e.g. 100\n\tparallaxBackgroundHorizontal: '',\n\tparallaxBackgroundVertical: ''\n\n});\n```\n\n\nThe configuration can be updated after initialization using the ```configure``` method:\n\n```javascript\n// Turn autoSlide off\nReveal.configure({ autoSlide: 0 });\n\n// Start auto-sliding every 5s\nReveal.configure({ autoSlide: 5000 });\n```\n\n\n### Dependencies\n\nReveal.js doesn't _rely_ on any third party scripts to work but a few optional libraries are included by default. These libraries are loaded as dependencies in the order they appear, for example:\n\n```javascript\nReveal.initialize({\n\tdependencies: [\n\t\t// Cross-browser shim that fully implements classList - https://github.com/eligrey/classList.js/\n\t\t{ src: 'lib/js/classList.js', condition: function() { return !document.body.classList; } },\n\n\t\t// Interpret Markdown in

elements\n\t\t{ src: 'plugin/markdown/marked.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },\n\t\t{ src: 'plugin/markdown/markdown.js', condition: function() { return !!document.querySelector( '[data-markdown]' ); } },\n\n\t\t// Syntax highlight for

 elements\n\t\t{ src: 'plugin/highlight/highlight.js', async: true, callback: function() { hljs.initHighlightingOnLoad(); } },\n\n\t\t// Zoom in and out with Alt+click\n\t\t{ src: 'plugin/zoom-js/zoom.js', async: true },\n\n\t\t// Speaker notes\n\t\t{ src: 'plugin/notes/notes.js', async: true },\n\n\t\t// Remote control your reveal.js presentation using a touch device\n\t\t{ src: 'plugin/remotes/remotes.js', async: true },\n\n\t\t// MathJax\n\t\t{ src: 'plugin/math/math.js', async: true }\n\t]\n});\n```\n\nYou can add your own extensions using the same syntax. The following properties are available for each dependency object:\n- **src**: Path to the script to load\n- **async**: [optional] Flags if the script should load after reveal.js has started, defaults to false\n- **callback**: [optional] Function to execute when the script has loaded\n- **condition**: [optional] Function which must return true for the script to be loaded\n\n\n### Ready Event\n\nA 'ready' event is fired when reveal.js has loaded all non-async dependencies and is ready to start navigating. To check if reveal.js is already 'ready' you can call `Reveal.isReady()`.\n\n```javascript\nReveal.addEventListener( 'ready', function( event ) {\n\t// event.currentSlide, event.indexh, event.indexv\n} );\n```\n\n\n### Presentation Size\n\nAll presentations have a normal size, that is the resolution at which they are authored. The framework will automatically scale presentations uniformly based on this size to ensure that everything fits on any given display or viewport.\n\nSee below for a list of configuration options related to sizing, including default values:\n\n```javascript\nReveal.initialize({\n\n\t...\n\n\t// The \"normal\" size of the presentation, aspect ratio will be preserved\n\t// when the presentation is scaled to fit different resolutions. Can be\n\t// specified using percentage units.\n\twidth: 960,\n\theight: 700,\n\n\t// Factor of the display size that should remain empty around the content\n\tmargin: 0.1,\n\n\t// Bounds for smallest/largest possible scale to apply to content\n\tminScale: 0.2,\n\tmaxScale: 1.5\n\n});\n```\n\n\n### Auto-sliding\n\nPresentations 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:\n\n```javascript\n// Slide every five seconds\nReveal.configure({\n  autoSlide: 5000\n});\n```\nWhen 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.\n\nYou can also override the slide duration for individual slides and fragments by using the ```data-autoslide``` attribute:\n\n```html\n\n\tAfter 2 seconds the first fragment will be shown.
\n\tAfter 10 seconds the next fragment will be shown.
\n\tNow, the fragment is displayed for 2 seconds before the next slide is shown.
\n
\n```\n\nWhenever the auto-slide mode is resumed or paused the ```autoslideresumed``` and ```autoslidepaused``` events are fired.\n\n\n### Keyboard Bindings\n\nIf you're unhappy with any of the default keyboard bindings you can override them using the ```keyboard``` config option:\n\n```javascript\nReveal.configure({\n  keyboard: {\n    13: 'next', // go to the next slide when the ENTER key is pressed\n    27: function() {}, // do something custom when ESC is pressed\n    32: null // don't do anything when SPACE is pressed (i.e. disable a reveal.js default binding)\n  }\n});\n```\n\n### Lazy Loading\n\nWhen 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.\n\nTo 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.\n\n```html\n\n  \n  \n  \n
\n```\n\n\n### API\n\nThe ``Reveal`` object exposes a JavaScript API for controlling navigation and reading state:\n\n```javascript\n// Navigation\nReveal.slide( indexh, indexv, indexf );\nReveal.left();\nReveal.right();\nReveal.up();\nReveal.down();\nReveal.prev();\nReveal.next();\nReveal.prevFragment();\nReveal.nextFragment();\n\n// Toggle presentation states, optionally pass true/false to force on/off\nReveal.toggleOverview();\nReveal.togglePause();\nReveal.toggleAutoSlide();\n\n// Change a config value at runtime\nReveal.configure({ controls: true });\n\n// Returns the present configuration options\nReveal.getConfig();\n\n// Fetch the current scale of the presentation\nReveal.getScale();\n\n// Retrieves the previous and current slide elements\nReveal.getPreviousSlide();\nReveal.getCurrentSlide();\n\nReveal.getIndices(); // { h: 0, v: 0 } }\nReveal.getProgress(); // 0-1\nReveal.getTotalSlides();\n\n// State checks\nReveal.isFirstSlide();\nReveal.isLastSlide();\nReveal.isOverview();\nReveal.isPaused();\nReveal.isAutoSliding();\n```\n\n### Slide Changed Event\n\nA '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.\n\nSome libraries, like MathJax (see [#226](https://github.com/hakimel/reveal.js/issues/226#issuecomment-10261609)), 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.\n\n```javascript\nReveal.addEventListener( 'slidechanged', function( event ) {\n\t// event.previousSlide, event.currentSlide, event.indexh, event.indexv\n} );\n```\n\n### Presentation State\n\nThe 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.\n\n```javascript\nReveal.slide( 1 );\n// we're on slide 1\n\nvar state = Reveal.getState();\n\nReveal.slide( 3 );\n// we're on slide 3\n\nReveal.setState( state );\n// we're back on slide 1\n```\n\n### Slide States\n\nIf you set ``data-state=\"somestate\"`` on a slide ````, \"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.\n\nFurthermore you can also listen to these changes in state via JavaScript:\n\n```javascript\nReveal.addEventListener( 'somestate', function() {\n\t// TODO: Sprinkle magic\n}, false );\n```\n\n### Slide Backgrounds\n\nSlides 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 `````` elements. Four different types of backgrounds are supported: color, image, video and iframe. Below are a few examples.\n\n```html\n\n\tAll CSS color formats are supported, like rgba() or hsl().
\n
\n\n\tThis slide will have a full-size background image.
\n
\n\n\tThis background image will be sized to 100px and repeated.
\n
\n\n\tVideo. Multiple sources can be defined using a comma separated list. Video will loop when the data-background-video-loop attribute is provided.
\n
\n\n\tEmbeds a web page as a background. Note that the page won't be interactive.
\n
\n```\n\nBackgrounds 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.\n\n\n### Parallax Background\n\nIf you want to use a parallax scrolling background, set the first two config properties below when initializing reveal.js (the other two are optional).\n\n```javascript\nReveal.initialize({\n\n\t// Parallax background image\n\tparallaxBackgroundImage: '', // e.g. \"https://s3.amazonaws.com/hakim-static/reveal-js/reveal-parallax-1.jpg\"\n\n\t// Parallax background size\n\tparallaxBackgroundSize: '', // CSS syntax, e.g. \"2100px 900px\" - currently only pixels are supported (don't use % or auto)\n\n\t// Amount of pixels to move the parallax background per slide step,\n\t// a value of 0 disables movement along the given axis\n\t// These are optional, if they aren't specified they'll be calculated automatically\n\tparallaxBackgroundHorizontal: 200,\n\tparallaxBackgroundVertical: 50\n\n});\n```\n\nMake sure that the background size is much bigger than screen size to allow for some scrolling. [View example](http://lab.hakim.se/reveal-js/?parallaxBackgroundImage=https%3A%2F%2Fs3.amazonaws.com%2Fhakim-static%2Freveal-js%2Freveal-parallax-1.jpg¶llaxBackgroundSize=2100px%20900px).\n\n\n\n### Slide Transitions\nThe 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:\n\n```html\n\n\tThis slide will override the presentation transition and zoom!
\n
\n\n\n\tChoose from three transition speeds: default, fast or slow!
\n
\n```\n\nYou can also use different in and out transitions for the same slide:\n\n```html\n\n    The train goes on … \n
\n \n    and on … \n
\n \n    and stops.\n
\n \n    (Passengers entering and leaving)\n
\n\n    And it starts again.\n
\n```\n\n\nNote that this does not work with the page and cube transitions.\n\n\n### Internal links\n\nIt'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 (``````):\n\n```html\nLink\nLink\n```\n\nYou 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.\n\n```html\n\n\n\n\n \n \n```\n\n\n### Fragments\nFragments 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\n\nThe default fragment style is to start out invisible and fade in. This style can be changed by appending a different class to the fragment:\n\n```html\n\n\tgrow
\n\tshrink
\n\tfade-out
\n\tvisible only once
\n\tblue only once
\n\thighlight-red
\n\thighlight-green
\n\thighlight-blue
\n
\n```\n\nMultiple 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.\n\n```html\n\n\t\n\t\tI'll fade in, then out\n\t\n
\n```\n\nThe display order of fragments can be controlled using the ```data-fragment-index``` attribute.\n\n```html\n\n\tAppears last
\n\tAppears first
\n\tAppears second
\n
\n```\n\n### Fragment events\n\nWhen a slide fragment is either shown or hidden reveal.js will dispatch an event.\n\nSome libraries, like MathJax (see #505), get confused by the initially hidden fragment elements. Often times this can be fixed by calling their update or render function from this callback.\n\n```javascript\nReveal.addEventListener( 'fragmentshown', function( event ) {\n\t// event.fragment = the fragment DOM element\n} );\nReveal.addEventListener( 'fragmenthidden', function( event ) {\n\t// event.fragment = the fragment DOM element\n} );\n```\n\n### Code syntax highlighting\n\nBy default, Reveal is configured with [highlight.js](http://softwaremaniacs.org/soft/highlight/en/) for code syntax highlighting. Below is an example with clojure code that will be syntax highlighted. When the `data-trim` attribute is present surrounding whitespace is automatically removed.\n\n```html\n\n\t\n(def lazy-fib\n  (concat\n   [0 1]\n   ((fn rfib [a b]\n        (lazy-cons (+ a b) (rfib b (+ a b)))) 0 1)))\n\t
\n
\n```\n\n### Slide number\nIf you would like to display the page number of the current slide you can do so using the ```slideNumber``` configuration value.\n\n```javascript\n// Shows the slide number using default formatting\nReveal.configure({ slideNumber: true });\n\n// Slide number formatting can be configured using these variables:\n//  h: current slide's horizontal index\n//  v: current slide's vertical index\n//  c: current slide index (flattened)\n//  t: total number of slides (flattened)\nReveal.configure({ slideNumber: 'c / t' });\n\n```\n\n\n### Overview mode\n\nPress \"Esc\" or \"o\" keys to toggle the overview mode on and off. While you're in this mode, you can still navigate between slides,\nas if you were at 1,000 feet above your presentation. The overview mode comes with a few API hooks:\n\n```javascript\nReveal.addEventListener( 'overviewshown', function( event ) { /* ... */ } );\nReveal.addEventListener( 'overviewhidden', function( event ) { /* ... */ } );\n\n// Toggle the overview mode programmatically\nReveal.toggleOverview();\n```\n\n### Fullscreen mode\nJust press »F« on your keyboard to show your presentation in fullscreen mode. Press the »ESC« key to exit fullscreen mode.\n\n\n### Embedded media\nEmbedded HTML5 `

All CSS color formats are supported, like rgba() or hsl().

This slide will have a full-size background image.

This background image will be sized to 100px and repeated.

Video. Multiple sources can be defined using a comma separated list. Video will loop when the data-background-video-loop attribute is provided.

Embeds a web page as a background. Note that the page won't be interactive.

This slide will override the presentation transition and zoom!

Choose from three transition speeds: default, fast or slow!

This video will use up the remaining space on the slide
