(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.cssorspinkit.min.cssto 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.cssorexamples.html - Add the
sk-centerutility class to the spinner to center it (it setsmargintoauto) - By default, the
widthandheightof all spinners are set to40px.background-coloris 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:
$ bower install spinkit
or npm:
$ npm install spinkit

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
Implementing a fallback spinner
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:
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:
if (!browserSupportsCSSProperty('animation')) {
// fallback…
}
