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

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:

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…
}
