All the content of the presentation will be created inside that element. It is not recommended to manipulate any of the styles, attributes or classes that are created by impress.js inside the Root Element after initialization. To change the duration of the transition between slides use `data-transition-duration="2000"` giving it a number of ms. It defaults to 1000 (1s). When authoring impress.js presentations, you should target some screen size, which you can define here. The default is 1024 x 768. You should write your CSS as if this is the screen size used for the presentation. When you present your presentation on a screen (or browser window) of different size, impress.js will automatically scale the presentation to fit the screen. The minimum and maximum limits to this scaling can also be defined here. All impress.js steps are wrapped inside a div element of 0 size! This means that in your CSS you can't use relative values for width and height (example: `width: 100%`) to define the size of step elements. You need to use pixel values. The pixel values used here correspond to the `data-width` and `data-height` given to the `#impress` root element. When the presentation is viewed on a larger or smaller screen, impress.js will automatically scale the steps to fit the screen. **NOTE:** The default width and height have been changed to target HD screens in v1.2.0. If you don't set target width and height explicitly, layout and dimensions of your presentations are likely to be affected. In order to get back the old target resolution, use:
``` ### Step Element A Step Element is an element that contains metadata that defines how it is going to be presented in the screen. A Step Element should contain a `.step` class and an optional `id` attribute. The content represents an html fragment that will be positioned at the center of the camera. In the Step Element, you can define a specific set of default attributes and positioning, that are documented below. **Example:** ```html
Aren’t you just bored with all those slides-based presentations?
``` #### 2D Coordinates Positioning (data-x, data-y) Define the pixel based position in which the **center** of the [Step Element](#step-element) will be positioned inside the infinite canvas. **Attributes** Attribute | Default | Explanation -------------------------|-----------|------------ data-x | 0 | X coordinate for step position data-y | 0 | Y coordinate for step position **Example:** ```html
Aren’t you just bored with all those slides-based presentations?
``` #### 2D Scaling (data-scale) Defines the scaling multiplier of the [Step Element](#step-element) relative to other Step Elements. For example, `data-scale="4"` means that the element will appear to be 4 times larger than the others. From the presentation and transitions point of view, it means that it will have to be scaled down (4 times) to make it back to its correct size. **Example:** ```html
then you should try

impress.js*

* no rhyme intended
``` #### 2D Rotation (data-rotate) Represents the amount of clockwise rotation of the element relative to 360 degrees. **Example:** ```html

It’s a presentation tool
inspired by the idea behind prezi.com
and based on the power of CSS3 transforms and transitions in modern browsers.

``` #### 3D Coordinates Positioning (data-z) Define the pixel based position in which the **center** of the [Step Element](#step-element) will be positioned inside the infinite canvas on the third dimension (Z) axis. For example, if we use `data-z="-3000"`, it means that the [Step Element](#step-element) will be positioned far away from the camera (by 3000px). **Example:** ```html

and tiny ideas

``` **Note:** The introduction of the [rel](src/plugins/rel/README.md) plugin includes a slight backward incompatible change. Previously the default value for `data-x`, `data-y` and `data-z` was zero. The `rel` plugin changes the default to inherit the value of the previous slide. This means, you need to explicitly set these values to zero, if they ever were non-zero. #### 3D Rotation (data-rotate-x, data-rotate-y, data-rotate-z) You can not only position a [Step Element](#step-element) in 3D, but also rotate it around any axis. **Example:** The example below will get rotated by -40 degrees (40 degrees anticlockwise) around X axis and 10 degrees (clockwise) around Y axis. You can of course rotate it around Z axis with `data-rotate-z` - it has exactly the same effect as `data-rotate` (these two are basically aliases). ```HTML

have you noticed it’s in 3D*?

* beat that, prezi ;)
``` #### 3D Rotation Order (data-rotate-order) The order in which the CSS `rotateX(), rotateY(), rotateZ()` transforms are applied matters. This is because each rotation is relative to the then current position of the element. By default the rotation order is `data-rotate-order="xyz"`. For some advanced uses you may need to change it. The demo presentation [3D rotations](examples/3D-rotations/index.html) sets this attribute to rotate some steps into positions that are impossible to reach with the default order. ## CSS ### 4D States (.past, .present and .future classes) The `.future` class is added to all [Step Elements](#step-element) that haven't been visited yet. **Example:** ```CSS .future { display: none; } ``` The `.present` class is added to the [Step Element](#step-element) that is currently at the center of the camera. This is useful to create animations inside the step once the camera navigates to it. **Example:** ```CSS .present .rotating { transform: rotate(-10deg); transition-delay: 0.25s; } ``` The `.past` class is added to all [Step Elements](#step-element) that have been visited at least once. **Example:** ```CSS .past { display: none; } ``` ### Current Active Step (.active class) The `.active` class is added to the [Step Element](#step-element) that is currently visible at the center of the camera. **Example:** ```CSS .step { opacity: 0.3; transition: opacity 1s; } .step.active { opacity: 1 } ``` At the same time, the `impress-on-*` class is added to the body element, the class name represents the active [Step Element](#step-element) id. This allows for custom global styling, since you can't match a CSS class backwards from the active [Step Element](#step-element) to the `body`. **Example:** ```CSS .impress-on-overview .step { opacity: 1; cursor: pointer; } .impress-on-step-1, .impress-on-step-2, .impress-on-step-3 { background: LightBlue; } ``` ### Progressive Enhancement (.impress-not-supported class) The `.impress-not-supported` class is added to the `body` element if the browser doesn't support the features required by impress.js to work, it is useful to apply some fallback styles in the CSS. It's not necessary to add it manually on the `body` element. If the script detects that the browser lacks important features it will add this class. It is recommended to add the class manually to the `body` element though, because that means that users without JavaScript will also get fallback styles. When impress.js script detects that the browser supports all required features, the `.impress-not-support` class will be removed from the `body` element. **Example:** ```CSS .impress-not-supported .step { display: inline-block; } ``` ## Plugins Many new features are implemented as plugins. The [Plugins documentation](src/plugins/README.md) is the starting place to learn about those, as well as the README.md of [each plugin](src/plugins/). ## JavaScript ### impress( [ id ] ) A factory function that creates the [ImpressAPI](#impressapi). Accepts a [`String`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) that represents the id of the root element in the page. If omitted, impress.js will lookup for the element with the id "impress" by default. **Example:** ```JavaScript var impressAPI = impress( "root" ); ``` ### ImpressAPI The main impress.js API that handles common operations of impress.js, listed below. #### .init() Initializes impress.js globally in the page. Only one instance of impress.js is supported per document. **Example:** ```JavaScript impress().init(); ``` Triggers the `impress:init` event in the [Root Element](#root-element) after the presentation is initialized. **Example:** ```JavaScript var rootElement = document.getElementById( "impress" ); rootElement.addEventListener( "impress:init", function() { console.log( "Impress init" ); }); impress().init(); ``` #### .tear() Resets the DOM to its original state, as it was before `init()` was called. This can be used to "unload" impress.js. A particular use case for this is, if you want to do dynamic changes to the presentation, you can do a teardown, apply changes, then call `init()` again. (In most cases, this will not cause flickering or other visible effects to the user, beyond the intended dynamic changes.) **Example:** ```JavaScript impress().tear(); ``` #### .next() Navigates to the next step of the presentation using the [`goto()` function](#impressgotostepindexstepelementidstepelement-duration). **Example:** ```JavaScript var api = impress(); api.init(); api.next(); ``` #### .prev() Navigates to the previous step of the presentation using the [`goto()` function](#impressgotostepindexstepelementidstepelement-duration). **Example:** ```JavaScript var api = impress(); api.init(); api.prev(); ``` #### .goto( stepIndex | stepElementId | stepElement, [ duration ] ) Accepts a [`Number`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number) that represents the step index. Navigates to the step given the provided step index. **Example:** ```JavaScript var api = impress(); api.init(); api.goto(7); ``` Accepts a [`String`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) that represents the [Step Element](#step-element) id. Navigates to the step given the provided [Step Element](#step-element) id. **Example:** ```JavaScript var api = impress(); api.init(); api.goto( "overview" ); ``` Accepts an [`HTMLElement`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement) that represents the [Step Element](#step-element). Navigates to the step given the provided [Step Element](#step-element). **Example:** ```JavaScript var overview = document.getElementById( "overview" ); var api = impress(); api.init(); api.goto( overview ); ``` Accepts an optional [Number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number) in the last argument that represents the duration of the transition in milliseconds. If not provided, the default transition duration for the presentation will be used. Triggers the `impress:stepenter` event in the [Root Element](#root-element) when the presentation navigates to the target [Step Element](#step-element). **Example:** ```JavaScript var rootElement = document.getElementById( "impress" ); rootElement.addEventListener( "impress:stepenter", function(event) { var currentStep = event.target; console.log( "Entered the Step Element '" + currentStep.id + "'" ); }); ``` Triggers the `impress:stepleave` event in the [Root Element](#root-element) when the presentation navigates away from the current [Step Element](#step-element). **Example:** ```JavaScript var rootElement = document.getElementById( "impress" ); rootElement.addEventListener( "impress:stepleave", function(event) { var currentStep = event.target; var nextStep = event.detail.next; console.log( "Left the Step Element '" + currentStep.id + "' and about to enter '" + nextStep.id ); }); ``` # Improve The Docs Did you find something that can be improved? Then [create an issue](https://github.com/impress/impress.js/issues/new) so that we can discuss it! ================================================ FILE: GettingStarted.md ================================================ # Introduction Welcome to impress.js! This presentation framework allows you to create stunning presentations with the power of CSS3 transformations. **NOTE:** This Guide is not made for you if you have never written HTML and/or CSS before. Knowing your way around in JavaScript certainly helps, but it is not a necessity. You may still continue this tutorial and try to understand what we do as you go. For more advanced and complete documentation, you might prefer the [DOCUMENTATION](DOCUMENTATION.md). # Getting started with impress.js ## Installation / acquiring the framework First of all, you need to know if you are going to have a WiFi connection when you hold your presentation. If you are not sure, please use the method where you download the file instead of the CDN. ### Including from CDN Loading the script from the CDN is quite straightforward. If you copy the example code below, you need to do nothing else; impress.js will be loaded automatically. **Direct links to different versions of the impress.js file** - V2.0.0: https://cdn.jsdelivr.net/gh/impress/impress.js@2.0.0/js/impress.js - V1.1.0: https://cdn.jsdelivr.net/gh/impress/impress.js@1.1.0/js/impress.js - Source: https://cdn.jsdelivr.net/gh/impress/impress.js/js/impress.js ### Download the file to your PC Head to the releases tab and download the source code as a zip or a tarball. Go ahead and unzip/untar it. You need to copy the folder */js/* into the folder you are working in. Optionally, to make your life a bit easier, you can also copy the */css/* folder into the same location. ## Setting up the project Open up your favorite text editor / IDE, for example, Visual Studio Code, Atom, Notepad++, ... Now, create a new file called *index.html* and create the basic HTML structure: ``` My first presentation

Your browser doesn't support the features required by impress.js, so you are presented with a simplified version of this presentation.

For the best experience please use the latest Chrome, Safari or Firefox browser.

My first Slide

``` Now, head into a file manager, navigate to the file you just created (*index.html*), and open it. You should end up in a browser where you should see "My first Slide" displayed. Since this isn't exciting, we won't change anything and will review what you just typed. What do these lines mean? Well, first things first, you should probably give your presentation a title. You may do this in normal HTML fashion by changing the *title* HTML tag. So now, we have reached the HTML body. You can see that it already belongs to a class. This class just tells impress.js that this is the body where the "fallback-message" should be displayed when it detects, that your browser does not support CSS3 and therefore impress.js won't work. You can easily omit that class though, including the "fallback-message" div with its content, if you only intend to use the presentation for yourself and you know about the fact that some browsers might not work. Now, probably the most important part of all is the *div* that belongs to the ```impress``` class. This *div* should contain all the HTML code you write, as everything outside that class will not be animated by impress.js. Finally, we load the ```impress.js``` script from your local copy (if you have one) or from the CDN, if you do not have a local copy, and execute ``` impress().init() ``` to initialize impress.js. Now, let's continue to explore more features of this amazing tool! ## Creating slides Creating slides is fairly easy. You create a *div* that belongs to the class ```step``` and you are off to the races! Let me give you an example: ```
Hello World
``` Now, if you reload the presentation, you start to see a \*slight\* problem. All your text is stacked... How do we work around that? Obviously, impress.js has an answer to it. You can add the following additional attributes to your div to make it work: Attribute | Explanation ----------------|------------ data-x | Position the element along the x-axis (from left to right) data-y | Position the element along the y-axis (from top to bottom) data-z | Position the element along the z-axis (3D-Effect, move the element behind another one) data-rotate | Rotate the element (if not using data-z!) data-rotate-x | Rotate the element along the x-axis data-rotate-y | Rotate the element along the y-axis data-rotate-z | Rotate the element along the z-axis data-scale | Scale the element. These are the basic positioning options in impress.js. All of the attributes take Strings as arguments, so be aware that you need to put quotation marks around the numbers! The *data-rotate* attributes take an angle in the form of a String as an argument. Now that you have created the slides, you might want to style them. This is where CSS comes into play. Add another file to your project called, e.g., ```style.css```. **NOTE:** Whatever you do, do not mess with the positioning and rotation of the div that belongs to the class *step*, but add a div inside of it, if you really have to mess with these properties. See the example below. Always position *steps* with the *data-* attribute! ```

Powerful, yet still simple

``` **NOTE:** You may also use negative numbers for all these properties! ## More advanced features You might want to change some default settings, like the transition speed, the width & height of the target screen, etc. This table is from the [DOCUMENTATION](DOCUMENTATION.md) and was slightly adapted. Attribute | Default | Explanation -------------------------|-----------|------------ data-transition-duration | 1000 (ms) | Speed of transition between steps. data-width | 1920 (px) | Width of target screen size. When presentation is viewed on a larger or smaller screen, impress.js will scale all content automatically. data-height | 1080 (px) | Height of target screen size. data-max-scale | 3 | Maximum scale factor. (Note that the default 1 will not increase content size on larger screens!) data-min-scale | 0 | Minimum scale factor. data-perspective | 1000 | Perspective for 3D rendering. See https://developer.mozilla.org/en/CSS/perspective ### **Renaming Steps** You can give each step an ID. The name of the ID will be displayed in the browser's navigation bar instead of the default *step-x*, where x is replaced by the current step number. This can be especially helpful when trying to jump between steps and go back to a previous one. If you want to know how to move to a specific slide, you should take a look at the [README](./src/plugins/goto/README.md) of the "Goto" plugin. # Using PLUGINS Impress.js is limited to everything we have discussed so far, along with some additional details; we won't cover them here. Check the [DOCUMENTATION](DOCUMENTATION.md) for that. impress.js has accumulated a lot of very useful plugins. You may find all of them [here](./src/plugins/)! Each Plugin has a README.md file, which you may read to get an idea of how to use it. Some plugins run unnoticed in the background, such as the *resize* plugin, which automatically resizes the presentation whenever the browser window changes size. Here, I will give you an overview of some of the plugins that impress.js includes by default. **NOTE:** As previously mentioned, if you'd like to get more info about how it works, take a look at the [DOCUMENTATION](DOCUMENTATION.md) or the README.md files of the plugins. ## [impressConsole](/src/plugins/impressConsole/README.md) This plugin opens up an additional browser tab that contains a speaker console. There you can see the current slide, the past slide, and your notes. You add notes to your presentation by adding a *div* that belongs to the class "notes" to your *div* that belongs to the class "step". ### **adding notes to your presentation** You may add notes to your presentation by adding a div of class *notes* into the div of class *step*, like so: ```
Some text that is being displayed on your slides
this won't be displayed in your presentation
``` Now that you have added the notes to your HTML, it is time to hide them. You need to add the following code to your CSS file (or in the style tag in the header): ``` .notes { display: none; } ``` To enter it, press P. ## [Goto](/src/plugins/goto/README.md) This plugin allows you to directly go to a certain step by either passing in a number or the ID of the step you'd like to go to. ## [Progress](/src/plugins/progress/README.md) This plugin, as its name implies, displays the progress in your presentation. ## [Blackout](/src/plugins/blackout/blackout.js) This plugin hides the screen when you press B, which is handy in many situations. ## Other plugins You may find the other plugins [here](/src/plugins/). It certainly helps if you familiarise yourself with the plugins. # Thank you for reading this If you want to know more, you can always read the [DOCUMENTATION](DOCUMENTATION.md) or, even better, read the Source Code and try to understand how it works! ================================================ FILE: LICENSE ================================================ The MIT License (MIT) Copyright (c) 2011-2016 Bartek Szopka Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

If you want to learn how to do this, you can find a how-to in the [Getting Started](GettingStarted.md) guide. - V2.0.0: https://cdn.jsdelivr.net/gh/impress/impress.js@2.0.0/js/impress.js - V1.1.0: https://cdn.jsdelivr.net/gh/impress/impress.js@1.1.0/js/impress.js - Source: https://cdn.jsdelivr.net/gh/impress/impress.js/js/impress.js ### Getting Started Guide Check out our new [Getting Started](GettingStarted.md) guide if you want a quick introduction to the project! ### Checking out and initializing the git repository git clone --recursive https://github.com/impress/impress.js.git cd impress.js Note: For a minimal checkout, omit the `--recursive` option. This will leave out extra plugins. **Stable releases** New features and fixes are continuously merged into the master branch, which is what the above command will check out. For the latest stable release, see the [Github Releases page](https://github.com/impress/impress.js/releases). ### Documentation Reference documentation of core impress.js features and API you can find it in [DOCUMENTATION.md](DOCUMENTATION.md). The [HTML source code](index.html) of the official [impress.js demo](http://impress.github.io/impress.js/) serves as a good example usage and contains comments explaining various features of impress.js. For more information about styling you can look into [CSS code](css/impress-demo.css) which shows how classes provided by impress.js can be used. Last but not least [JavaScript code of impress.js](js/impress.js) has some useful comments if you are interested in how everything works. Feel free to explore! ### Official demo [impress.js demo](http://impress.github.io/impress.js/) by [@bartaz](http://twitter.com/bartaz) ### Examples and demos The [Classic Slides](http://impress.github.io/impress.js/examples/classic-slides/) demo is targeted towards beginners, or can be used as a template for presentations that look like the traditional PowerPoint slide deck. Over time, it also grew into the example presentation that uses most of the features and addons available. More examples and demos can be found on [Examples and demos wiki page](http://github.com/impress/impress.js/wiki/Examples-and-demos). Feel free to add your own example presentations (or websites) there. ### Other tutorials and learning resources If you want to learn even more there is a [list of tutorials and other learning resources](https://github.com/impress/impress.js/wiki/impress.js-tutorials-and-other-learning-resources) on the wiki, too. There is also a book available about [Building impressive presentations with impress.js](http://www.packtpub.com/building-impressive-presentations-with-impressjs/book) by Rakhitha Nimesh Ratnayake. You may want to check out the sibling project [Impressionist](https://github.com/henrikingo/impressionist): a 3D GUI editor that can help you in creating impress.js presentations. ### Mailing list You're welcome to ask impress.js related questions on the [impressionist-presentations](https://groups.google.com/forum/#!forum/impressionist-presentations) mailing list. REPOSITORY STRUCTURE -------------------- * [index.html](index.html): This is the official impress.js demo, showcasing all of the features of the original impress.js, as well as some new plugins as we add them. * As already mentioned, this file is well commented and acts as the official tutorial. * [examples/](examples/): Contains several demos showcasing additional features available. * [Classic Slides](examples/classic-slides/index.html) is a simple demo that you can use as template if you want to create very simple, rectangular, PowerPoint-like presentations. * [src/](src/): The main file is [src/impress.js](src/impress.js). Additional functionality is implemented as plugins in [src/plugins/](src/plugins/). * See [src/plugins/README.md](src/plugins/README.md) for information about the plugin API and how to write plugins. * [test/](test/): Contains QUnit and Syn libraries that we use for writing tests, as well as some test coverage for core functionality. (Yes, more tests are much welcome.) Tests for plugins are in the directory of each plugin. * [js/](js/): Contains [js/impress.js](js/impress.js), which contains a concatenation of the core `src/impress.js` and all the plugins. Traditionally this is the file that you'll link to in a browser. In fact both the demo and test files do exactly that. * [css/](css/): Contains a CSS file used by the demo. This file is **not required for using impress.js** in your own presentations. Impress.js creates the CSS it needs dynamically. * [extras/](extras/) contains plugins that for various reasons aren't enabled by default. You have to explicitly add them with their own `script` element to use them. * [build.js](build.js): Simple build file that creates `js/impress.js`. It also creates a minified version `impress.min.js`, but that one is not included in the github repository. * [package.json](build.js): An NPM package specification. This was mainly added so you can easily install [buildify](https://www.npmjs.com/package/buildify) and run `node build.js`. Other than the build process, which is really just doing roughly `cat src/impress.js src/plugins/*/*.js > js/impress.js`, and testing, `impress.js` itself doesn't depend on Node or any NPM modules. WANT TO CONTRIBUTE? --------------------- For developers, once you've made changes to the code, you should run these commands for testing: npm install npm run all Note that running `firefox qunit_test_runner.html` is usually more informative than running `karma` with `npm run test`. They both run the same tests. More info about the [src/](src/) directory can be found in [src/plugins/README.md](src/plugins/README.md). ### Requirements * >= node 7.6 * npm ABOUT THE NAME ---------------- impress.js name is [courtesy of @skuzniak](http://twitter.com/skuzniak/status/143627215165333504). It's an (un)fortunate coincidence that an Open/LibreOffice presentation tool is called Impress ;) Reference API -------------- See the [Reference API](DOCUMENTATION.md) BROWSER SUPPORT ----------------- The design goal for impress.js has been to showcase awesome CSS3 features as found in modern browser versions. We also use some new DOM functionality, and specifically do not use jQuery or any other JavaScript libraries, nor our own functions, to support older browsers. In general, recent versions of Firefox and Chrome are known to work well. Reportedly IE now works too. The typical use case for impress.js is to create presentations that you present from your own laptop, with a browser version you know works well. Some people also use impress.js successfully to embed animations or presentations in a web page, however, be aware that in this some of your visitors may not see the presentation correctly, or at all. In particular, impress.js makes use of the following JS and CSS features: * [DataSet API](http://caniuse.com/#search=dataset) * [ClassList API](http://caniuse.com/#search=classlist) * [CSS 3D Transforms](http://caniuse.com/#search=css%203d) * [CSS Transitions](http://caniuse.com/#search=css%20transition) COPYRIGHT AND LICENSE --------------------- Copyright 2011-2012 Bartek Szopka (@bartaz), 2016-2023 Henrik Ingo (@henrikingo) and [70+ other contributors](https://github.com/impress/impress.js/graphs/contributors) Released under the MIT [License](LICENSE) ================================================ FILE: build.js ================================================ const fs = require('fs'); var ls = require('ls'); var path = require('path'); var Terser = require("terser"); var files = ['src/impress.js']; // Libraries from src/lib files.push('src/lib/gc.js', 'src/lib/util.js', 'src/lib/rotation.js') // Plugins from src/plugins files.push('src/plugins/autoplay/autoplay.js', 'src/plugins/blackout/blackout.js', 'src/plugins/extras/extras.js', 'src/plugins/form/form.js', 'src/plugins/fullscreen/fullscreen.js', 'src/plugins/goto/goto.js', 'src/plugins/bookmark/bookmark.js', 'src/plugins/help/help.js', 'src/plugins/impressConsole/impressConsole.js', 'src/plugins/media/media.js', 'src/plugins/mobile/mobile.js', 'src/plugins/mouse-timeout/mouse-timeout.js', 'src/plugins/navigation/navigation.js', 'src/plugins/navigation-ui/navigation-ui.js', 'src/plugins/progress/progress.js', 'src/plugins/rel/rel.js', 'src/plugins/resize/resize.js', 'src/plugins/skip/skip.js', 'src/plugins/stop/stop.js', 'src/plugins/substep/substep.js', 'src/plugins/touch/touch.js', 'src/plugins/toolbar/toolbar.js') var output = files.map((f)=>{ return fs.readFileSync(f).toString(); }).join('\n') var filename = 'js/impress.js'; fs.writeFileSync(filename, '// This file was automatically generated from files in src/ directory.\n\n' + output) console.log(filename); // terser --compress --mangle --comments '/^!/' --source-map --output js/impress.min.js js/impress.js var code = fs.readFileSync('js/impress.js').toString(); var options = { sourceMap: { filename: 'js/impress.js', url: 'js/impress.min.js.map' }, output: { comments: /^!/ } }; var result = Terser.minify({'js/impress.js': code}, options); filename = 'js/impress.min.js'; fs.writeFileSync(filename, result.code); console.log(filename); filename = 'js/impress.min.js.map'; fs.writeFileSync(filename, result.map); console.log(filename); /* Auto generate an index.html that lists all the directories under examples/ * This is useful for gh-pages, so you can link to http://impress.github.io/impress.js/examples */ var html_list = '\n' var html = '\n\nExample presentations\n\n' html += '

The best way to do this would be to use JavaScript, show a delayed hint for a first time users, then hide it and store a status in cookie or localStorage... But I wanted to have some CSS fun and avoid additional scripting... Let me explain it first, so maybe the transition magic will be more readable when you read the code. First of all I wanted the hint to appear only when user is idle for a while. You can't detect the 'idle' state in CSS, but I delayed a appearing of the hint by 5s using transition-delay. You also can't detect in CSS if the user is a first-time visitor, so I had to make an assumption that I'll only show the hint on the first step. And when the step is changed hide the hint, because I can assume that user already knows how to navigate. To summarize it - hint is shown when the user is on the first step for longer than 5 seconds. The other problem I had was caused by the fact that I wanted the hint to fade in and out. It can be easily achieved by transitioning the opacity property. But that also meant that the hint was always on the screen, even if totally transparent. It covered part of the screen and you couldn't correctly clicked through it. Unfortunately you cannot transition between display `block` and `none` in pure CSS, so I needed a way to not only fade out the hint but also move it out of the screen. I solved this problem by positioning the hint below the bottom of the screen with CSS transform and moving it up to show it. But I also didn't want this move to be visible. I wanted the hint only to fade in and out visually, so I delayed the fade in transition, so it starts when the hint is already in its correct position on the screen. I know, it sounds complicated ... maybe it would be easier with the code? */ .hint { /* We hide the hint until presentation is started and from browsers not supporting impress.js, as they will have a linear scrollable view ... */ display: none; /* ... and give it some fixed position and nice styles. */ position: fixed; left: 0; right: 0; bottom: 200px; background: rgba(0,0,0,0.5); color: #EEE; text-align: center; font-size: 50px; padding: 20px; z-index: 100; /* By default we don't want the hint to be visible, so we make it transparent ... */ opacity: 0; /* ... and position it below the bottom of the screen (relative to it's fixed position) */ -webkit-transform: translateY(400px); -moz-transform: translateY(400px); -ms-transform: translateY(400px); -o-transform: translateY(400px); transform: translateY(400px); /* Now let's imagine that the hint is visible and we want to fade it out and move out of the screen.

Your browser doesn't support the features required by impress.js, so you are presented with a simplified version of this presentation.

For the best experience please use the latest Chrome, Safari or Firefox browser.

2D navigation

  • Impress.js allows you to layout your presentation in a 3D space
  • The goto plugin allows you to specify non-linear navigation!
  • This demo can be navigated by
    • continuously pressing Space
    • continuously pressing Right Arrow
    • continuously pressing Down Arrow
    • (or freely, pressing Up, Down, Right, Left as you choose)
  • It's up to you to decide which is the better structure

Using bookmark hotkeys

  • The bookmark plugin also allows you to specify non-linear navigation, in a different way.
  • This demo can also be navigated by
    • pressing 1 2 3 4 5 6 7 8 9 to fast travel directly
    • pressing J J J, K K K, L L L to cycle vertically
    • pressing U U U, I I I, O O O to cycle horizontally
    • pressing Z or [ to zoom out to the full view
    • pressing 0 to come back to this text
  • It's up to you to decide which is the better structure

Choosing a treat

  • You can choose your preferred treat from:
    • Ice cream
    • Crisps
    • Apple pie
  • We will make a structured pro's & con's analysis to arrive at a conclusion

Ice cream

  • Cold
  • Creamy
  • Vanilla or flavored
  • Caramel sauce, jams & other toppings

Ice cream: Pro's

  • Great for dessert or snack
  • Great in the Summer

Ice cream: Con's

  • Not so great in the Winter
  • If you're allergic to lactose/milk
  • Diet alternatives are not real ice cream

Crisps

  • Potatoes fried in oil and salted
  • Various flavors
  • Dips
  • Can be used as ingredient in subs (Cliff Huxtable style)

Crisps: Pro's

  • Simple yet tasty concept
  • Great for snack
  • Salty / spicy (not sweet)
  • Finger food
  • Diet alternatives are often ok

Crisps: Con's

  • Commonly not used as dessert
  • Not sweet

Apple pie

  • Apple's in a pie
  • Many recipes exist. (Grandma's is the best.)
  • Vanilla sauce or cream on top

Apple pie: Pro's

  • Great for dessert
  • Or just with a cup of tea or glass of milk
  • Best when warm

Apple pie: Con's

  • I'm allergic to apple (but a small slice is worth it)
  • Not finger food

Conclusion

Can I choose all three ;-)

Slide one

This is a ring of 8 slides.

It's easy constucted with data-rel-position="relative" without calculates the coordinates of all slides.

Slide two

The position of this slide is calculated as relatived position and rotation of the first slide.

The following slides don't need to set any position attributes, they are inherit from this slide.

Slide three

Slide four

Slide five

Slide six

Slide seven

Slide eight

Slide one

This is another ring of slides.

Except for the this slide, its code is just cloned from the yellow ring.

Just change the position of first slide, all the following slides are position relatived to it.

A Study in 3D Rotations

Unlike the x/y/z coordinates (aka translations), the rotate-x/y/z rotations are applied in a specific order, and order matters. This demo presentation exhibits the use of the new data-rotate- order attribute. Instead of the default "xyz" order, the steps use the reversed "zyx" order in applying rotations around each axis. Some of the steps (3 & 7), are in positions that are not possible with the default "xyz" order.

It happens a lot in Chrome. I don't remember if I've seen it in Firefox. Sometimes the element positioned in 3D (especially when it's moved back along Z axis) is not clickable, because it falls 'behind' the element. To prevent this, I decided to make non clickable by setting pointer-events property to `none` value. Value if this property is inherited, so to make everything else clickable I bring it back on the #impress element. If you want to know more about `pointer-events` here are some docs: https://developer.mozilla.org/en/CSS/pointer-events There is one very important thing to notice about this workaround - it makes everything 'unclickable' except what's in #impress element. So use it wisely ... or don't use at all. */ .impress-enabled { pointer-events: none } .impress-enabled #impress { pointer-events: auto } .impress-enabled #impress-toolbar { pointer-events: auto } .impress-enabled #impress-console-button { pointer-events: auto } ================================================ FILE: examples/classic-slides/css/fonts.css ================================================ /* latin-ext */ @font-face { font-family: 'Cutive Mono';

Any element with the class="notes" will not be displayed. This can be used for speaker notes. In fact, the impressConsole plugin will show it in the speaker console!

Table of Contents

Table of Contents, with links to other slides of this same presentation.

Note that instead of absolute positioning we use relative positioning, with the data-rel-x and data-rel-y attributes. This means the step is positioned relative to the foregoing step. In other words, this is equivalent to data-x="0" data-y="-3000".

A slide with text

This slide has a few paragraphs
(p element) of normal text.

Personally I like centered or even justified text, as it looks less boring. This can of course be set in the css file.

I really like the style on links in these presentations. I modified the border to be beveled, but it's mostly from @bartaz' original demo. @bartaz is the creator of impress.js.

In this slide, we don't even specify the relative position, rather that too is inherited. So this slide will again be 1000px to the right of the previous one.

Bullet points

  • A slide with bullet points. This is the first point.
  • Second point
  • Third point. Under this point we also have some sub-bullets:
    • Sub-bullet 1
    • Sub-bullet 2

A blockquote & image

We use data-rel-position="relative" to make data-rel-rotate-* work, and make data-rel-x/data-rel-y/data-rel-y be calculated at the coordination related to previous slide. The relative position and rotation will be inherited by following slides, so it's not necessary to repeat it again and again.

More text styles

As usual, use em to emphasize,
strong for strong, u for underline,
strike for strikethrough and q for inline quotations.

If you're a software engineer like me, you will often use the <code> tag for monospaced inline text.

Items on the slide can

And zoom in

...just like in PowerPoint. Yeah, I know I'm being lame, but it was fun to learn to do this in CSS3.

This step here doesn't introduce anything new when it comes to data attributes, but you should notice in the demo that some words of this text are being animated. It's a very basic CSS transition that is applied to the elements when this step element is reached.

At the very beginning of the presentation all step elements are given the class of `future`. It means that they haven't been visited yet.

When the presentation moves to given step `future` is changed to `present` class name. That's how animation on this step works - text moves when the step has `present` class.

Finally when the step is left the `present` class is removed from the element and `past` class is added.

So basically every step element has one of three classes: `future`, `present` and `past`. Only one current step has the `present` class.

This step zoom in to left bottom of previous slide to see to small text.

It's a empty and transparent.

data-rel-reset is used to prevent this step from inheriting the relative positioning from previous slide.

Add-ons

This version of impress.js includes several add-ons, striving to make this a full featured presentation app.

The previous step breaks the slide flow, changes the relative position and rotation.

This slide use data-rel-to to inherit relative position and rotation from the slide before previous slide.

Impress.js plugins

  • A new plugin framework allows for rich extensibility, without bloating the core rendering library.
    • Press 'P' to open a presenter console.
    • When you move the mouse, navigation controls are visible on your bottom right
    • Autoplay makes the slides advance after a timeout
    • Relative positioning plugin is often a more convenient way to position your slides when editing. (See html for this presentation.)

This presentation also uses speaker notes. They are not visible in the presentation, but shown in the impress console.

If you pressed P only now, this is the first time you see these notes. In fact, there has been notes on preceding slides as well. You can use the navigation controls at the bottom of the impress console to browse back to them.

And did you notice how those bullet points appear one by one as you press space/arrow? That's another plugin, called substeps.

Highlight.js


        // `init` API function that initializes (and runs) the presentation.
        var init = function () {
            if (initialized) { return; }
            execPreInitPlugins();
            
            // First we set up the viewport for mobile devices.
            // For some reason iPad goes nuts when it is not done properly.
            var meta = $("meta[name='viewport']") || document.createElement("meta");
            meta.content = "width=device-width, minimum-scale=1, maximum-scale=1, user-scalable=no";
            if (meta.parentNode !== document.head) {
                meta.name = 'viewport';
                document.head.appendChild(meta);
            }

The Highlight.js library provides really nice color coding of source code. It automatically applies to any code inside a <pre><code> element.

Highlight.js is found under the extras/ directory, since it is an independent third party plugin, not really an impress.js plugin. You have to include it via it's own <link> and <script> tags.

Mermaid.js, likewise in extras/ directory, draws SVG diagrams from a MarkDown-like syntax. To learn more about it read the fine manual.
# Markdown.js * [Markdown.js](https://github.com/evilstreak/markdown-js) integration: for authors in a hurry! * ...or lazy ;-) * Jot down bullet points in *Markdown* * ...have it automatically converted to HTML * Markdown is converted into a presentation client side, in the browser. This is unlike existing tools like [Hovercraft](https://github.com/regebro/hovercraft) and markdown-impress where you generate a new html file on the command line. * [A more advanced Markdown presentation is here.](../markdown/)
  • Remember, in impress.js the full power of HTML5, CSS3 & JavaScript is always at your fingertips!
  • For example, you can use tables, forms, or dynamic charts as you would on any web page:

# Markdown ## to author Impress.js presentations * This presentation was written entirely in Markdown * Added by popular request * Easy way to make quick, simple yet aesthetic, presentations * Authoring without all the clutter of HTML ----- # Markdown.js * Provided by [Markdown.js](https://github.com/evilstreak/markdown-js) in [extras/](https://github.com/impress/impress.js/tree/master/extras) * Jot down your bullet points in *Markdown* & have it automatically converted to HTML * Note: The Markdown is converted into a presentation client side, in the browser. This is unlike existing tools like [Hovercraft](https://github.com/regebro/hovercraft) and markdown-impress where you generate a new html file on the command line. * This combines the ease of typing Markdown with the full power of impress.js HTML5+CSS3+JavaScript! ----- # Styles * You can use *italics* & **bold** * ...and `code` ----- # A blockquote & image ![Mother Teresa holding a newborn baby](images/3476636111_c551295ca4_b.jpg) > Spread love everywhere you go. > Let no one ever come to you without leaving happier. *-- Mother Teresa* Image credit: [Peta de Aztlan](https://www.flickr.com/photos/peta-de-aztlan/3476636111/)@Flickr. CC-BY 2.0 ----- # Code When also using [Highlight.js](https://highlightjs.org/) integration, code blocks in Markdown are converted to HTML first, then colored by Highlight.js: // `init` API function that initializes (and runs) the presentation. var init = function () { if (initialized) { return; } execPreInitPlugins(); // First we set up the viewport for mobile devices. // For some reason iPad goes nuts when it is not done properly. var meta = $("meta[name='viewport']") || document.createElement("meta"); meta.content = "width=device-width, minimum-scale=1, maximum-scale=1, user-scalable=no"; if (meta.parentNode !== document.head) { meta.name = 'viewport'; document.head.appendChild(meta); } ----- # Slide separator * 5 dashes are used to separate slides: `-----` * Attributes from `div.step` element are simply repeated. * Better use relative positioning, lest your slides will all be on top of each other. * If you need to set some attributes, just use HTML and create a div element, then write Markdown inside each div.
# Title slide ## This slide has different CSS class than the previous ones
# Simplicity of Markdown & Full power of Impress.js * This slide sets its own `rotate`, `x`, `y`, and even `z` coordinates * Note that the Mother Teresa slide earlier was pimped with some custom CSS, all the while the content was written in simple Markdown.
This is an example of a slide with a specific Markdown dialect. ===============================================================

CSS & JavaScript magic

Just to emphasize my point, this last slide allows you to use a JavaScript powered menu to toggle the CSS style:

Your browser doesn't support the features required by impress.js, so you are presented with a simplified version of this presentation.

For the best experience please use the latest Chrome, Safari or Firefox browser.

Aren’t you just bored with all those slides-based presentations?
Don’t you think that presentations given in modern browsers shouldn’t copy the limits of ‘classic’ slide decks?
Would you like to impress your audience with stunning visualization of your talk?
then you should try

impress.js*

* no rhyme intended

It’s a presentation tool
inspired by the idea behind prezi.com
and based on the power of CSS3 transforms and transitions in modern browsers.

visualize your big thoughts

and tiny ideas

by positioning, rotating and scaling them on an infinite canvas

the only limit is your imagination

All classes are removed when leaving * a step. * * - Introduce the following new data attributes: * * - data-media-autoplay="true": Autostart media when entering its step. * - data-media-autostop="true": Stop media (= pause and reset to start), when leaving its * step. * - data-media-autopause="true": Pause media but keep current time when leaving its step. * * When these attributes are added to a step they are inherited by all media on this step. * Of course this setting can be overwritten by adding different attributes to inidvidual * media. * * The same rule applies when this attributes is added to the root element. Settings can be * overwritten for individual steps and media. * * Examples: * - data-media-autoplay="true" data-media-autostop="true": start media on enter, stop on * leave, restart from beginning when re-entering the step. * * - data-media-autoplay="true" data-media-autopause="true": start media on enter, pause on * leave, resume on re-enter * * - data-media-autoplay="true" data-media-autostop="true" data-media-autopause="true": start * media on enter, stop on leave (stop overwrites pause). * * - data-media-autoplay="true" data-media-autopause="false": let media start automatically * when entering a step and let it play when leaving the step. * * -
...
* All media is startet automatically on all steps except the one that has the * data-media-autoplay="false" attribute. * * - Pro tip: Use
