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:

$ 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…
}
