FILE: CHANGELOG.md
================================================
# 2.0.1

* Fixed: Chase spinner's HTML snippet now has the correct number of children

# 2.0.0

* New: Added examples.html, with an overview of all spinners
* New: Added a brand new chase spinner
* New: Added spinkit.min.css
* Fixed: `inline-block` is no longed used to position any spinners (decoupling spacing from any potential font effects)
* Changed: Most spinners now have more distinct and shorter names
* Changed: No positioning is now applied by default on any of the spinners (center the spinner with the utility class `sk-center`)
* Changed: All elements now only have one single class
* Changed: No more dependencies. gulp, npm, node, etc. is not required to build this project. There's nothing to build
* Changed: No more SCSS. All configuration is now done through CSS vars
* Fixed: All keyframe animations are now named after the elements/classes that are using them

# 1.2.5

* Fixed: Add folding cube spinner (11) to combined CSS file

# 1.2.4

* Fixed: Borked gulp script (#106)
* Fixed: Moved changes made in CSS, to SCSS

# 1.2.3

* Fixed: More exact (33% -> 33.33%) cube dimensions for cube grid spinner
* Fixed: Comment format for HTML inside CSS, for easier copy and pasting (removed * at the beginning of each row)

# 1.2.2

* Fixed: Use variable for spinner size (defaults to 40px)

# 1.2.1

* Fixed: Two spinners were slightly broken on Android
* Changed: Bumped default top and bottom margin to 40px

# 1.2.0

* Added: Folding cube spinner
* Fixed: Lowercase in package name

# 1.1.0

* Removed one spinner (circle with rotating circle, not polished enough)
* Cleaned up the CSS
* Added more SCSS variables to more easily customize spinners
* Introduced SCSS `@for` loops to more easily change timing of spinners
* Removed moot `version` property from bower.json


# 1.0.1

* Fix: Missed sass variables for background-color

# [SpinKit](http://tobiasahlin.com/spinkit/)

Simple loading spinners animated with CSS. See [demo](http://tobiasahlin.com/spinkit/). SpinKit only uses (`transform` and `opacity`) CSS animations to create smooth and easily customizable animations.

## Usage

- Add `spinkit.css` or `spinkit.min.css` to your project (or copy-paste the CSS that you need for your spinner—there are no dependencies between spinners, no shared classes, and no shared animations, etc, so it should be fairly straight-forward to extract only the code that you need)
- Add a spinner to your project by copy-pasting HTML from `spinkit.css` or `examples.html`
- Add the `sk-center` utility class to the spinner to center it (it sets `margin` to `auto`)
- By default, the `width` and `height` of all spinners are set to `40px`. `background-color` is set to `#333`.
- Configure the spinner by overwriting the CSS variables, primarily `--sk-size` (spinner width & height) and `--sk-color` (spinner color). If you need broader browser support, remove the CSS variables.

You can include SpinKit to your project with `bower`:

```bash
$ bower install spinkit
```

or npm:

```bash
$ npm install spinkit
```

## Spinners

Given that you have included `spinkit.min.css` in your project, these snippets will produce the different spinners:

### Plane

```html
<div class="sk-plane"></div>
```

### Chase

```html
<div class="sk-chase">
  <div class="sk-chase-dot"></div>
  <div class="sk-chase-dot"></div>

## Web browser compatibility

SpinKit uses CSS animations and variables:

- CSS keyframes animations [are at +96.5% global support](http://caniuse.com/#feat=css-animation)
- CSS variables [are at +91.8% global support](https://caniuse.com/#feat=css-variables)

### Implementing a fallback spinner

How do you know if you need to provide a fallback? You can check for animation support with [Modernizr](http://modernizr.com), or manually check for the `animation` property, and replace the spinner with a GIF if it's not supported:

```javascript
function browserSupportsCSSProperty(propertyName) {
  var elm = document.createElement('div');
  propertyName = propertyName.toLowerCase();

  if (elm.style[propertyName] != undefined)
    return true;

  var propertyNameCapital = propertyName.charAt(0).toUpperCase() + propertyName.substr(1),
    domPrefixes = 'Webkit Moz ms O'.split(' ');

  for (var i = 0; i < domPrefixes.length; i++) {
    if (elm.style[domPrefixes[i] + propertyNameCapital] != undefined)
      return true;
  }

  return false;
}
```

Use it to check for `animation` support:

```javascript
if (!browserSupportsCSSProperty('animation')) {
  // fallback…
}
```
