它是一个基于在新的支持CSS3变换和过渡效果的浏览器下的演示框架，灵感来自于prezi.com.如果你已经厌烦了使用PowerPoint制作PPT，那么impress.js是一个非常 好的选择，用它做的PPT更加直观，效果也非常不错。

警告

如果你无话可说impress.js也无能为力 ;)

git clone --recursive https://github.com/jsgang/impress.js.git
cd impress.js

提示: 如果你不需要扩展插件, 可以删除选项 --recursive.

impress.js demo by @bartaz

The 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.

Feel free to add your own example presentations (or websites) there.

If you want to learn even more there is a list of tutorials and other learning resources on the wiki, too.

There is also a book available about Building impressive presentations with impress.js by Rakhitha Nimesh Ratnayake.

You may want to check out the sibling project Impressionist: a 3D GUI editor that can help you in creating impress.js presentations.

You're welcome to ask impress.js related questions on the impressionist-presentations mailing list.

• 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/: Contains several demos showcasing additional features available.
  • Classic Slides is a simple demo that that you can use as template if you want to create very simple, rectangular, PowerPoint-like presentations.
• src/: The main file is src/impress.js. Additional functionality is implemented as plugins in src/plugins/.
  • See src/plugins/README.md for information about the plugin API and how to write plugins.
• 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/: Contains 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/: 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/ 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: 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: An NPM package specification. This was mainly added so you can easily install 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.
• bower.json: A Bower package file. We also don't depend on Bower, but provide this file if you want to use it.

For developers, once you've made changes to the code, you should run these commands for testing:

npm run build
npm run test
npm run lint

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/ directory can be found in src/plugins/README.md.

It's an (un)fortunate coincidence that a Open/LibreOffice presentation tool is called Impress ;)

See the Reference API

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
• ClassList API
• CSS 3D Transforms
• CSS Transitions
