Loaders.css

Delightful and performance-focused pure css loading animations. ### What is this? [See the demo](http://connoratherton.com/loaders) A collection of loading animations written entirely in css. Each animation is limited to a small subset of css properties in order to avoid expensive painting and layout calculations. I've posted links below to some fantastic articles that go into this in a lot more detail. ### Install ``` bower install loaders.css ``` ``` npm i --save-dev loaders.css ``` ### Usage ##### Standard - Include `loaders.min.css` - Create an element and add the animation class (e.g. `
`) - Insert the appropriate number of `
`s into that element ##### jQuery (optional) - Include `loaders.min.css`, jQuery, and `loaders.css.js` - Create an element and add the animation class (e.g. `
`) - `loaders.js` is a simple helper to inject the correct number of div elements for each animation - Enjoy ### Customising ##### Changing the background color Add styles to the correct child `div` elements ``` css .ball-grid-pulse > div { background: orange; } ``` ### Browser support Check the [can I use](http://caniuse.com/#search=css-animation) [tables](http://caniuse.com/#search=css-transform). All recent versions of the major browsers are supported and it has support back to IE9. Note: The loaders aren't run through autoprefixer, see this [issue](https://github.com/ConnorAtherton/loaders.css/issues/18). IE 11 | Firefox 36 | Chrome 41 | Safari 8 ------ | ---------- | --------- | -------- ✔ | ✔ | ✔ | ✔ ### Contributing Pull requests are welcome! Create another file in `src/animations` and load it in `src/loader.scss`. In a separate tab run `gulp --require coffee-script/register`. Open `demo/demo.html` in a browser to see your animation running. ### Further research - http://www.paulirish.com/2012/why-moving-elements-with-translate-is-better-than-posabs-topleft/ - http://aerotwist.com/blog/pixels-are-expensive/ - http://www.html5rocks.com/en/tutorials/speed/high-performance-animations/ - http://frontendbabel.info/articles/webpage-rendering-101/ ### Inspired by loaders.css A few other folks have taken loaders and ported them elsewhere. - **React** - [Jon Jaques](https://github.com/jonjaques) built a React demo you can check out [here](https://github.com/jonjaques/react-loaders) - **Angular** - [the-corman](https://github.com/the-cormoran/angular-loaders) created some directives for angular, as did [Masadow](https://github.com/Masadow) in [this pr](https://github.com/ConnorAtherton/loaders.css/pull/50) - **iOS** - [ninjaprox](https://github.com/ninjaprox/NVActivityIndicatorView) and [ontovnik](https://github.com/gontovnik/DGActivityIndicatorView) - **Android** - [Jack Wang](https://github.com/81813780/AVLoadingIndicatorView) created a library and [technofreaky](https://github.com/technofreaky/Loaders.CSS-Android-App) created an app ### Licence The MIT License (MIT) Copyright (c) 2015 Connor Atherton 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.
