SpinKit

Simple loading spinners animated with CSS. See demo. 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
`

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

Web browser compatibility

SpinKit uses CSS animations and variables:

- CSS keyframes animations are at +96.5% global support
- CSS variables are at +91.8% global support

How do you know if you need to provide a fallback? You can check for animation support with Modernizr, 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…
}
