spin.js is an animated CSS3 loading spinner. You can adjust every single parameter: number of lines, length and width of lines, radius, trail, speed of spinning, and whether there’s a shadow or not.


  • No images, no external CSS 
  • No dependencies (jQuery is supported, but not required) 
  • Highly configurable Resolution independent 
  • Uses VML as fallback in old IEs 
  • Uses @keyframe animations, falling back to setTimeout() 
  • Works in all major browsers, including IE6 
  • MIT License 

Spin.js dynamically creates spinning activity indicators that can be used as resolution-independent replacement for AJAX loading GIFs.

The spin() method creates the necessary HTML elements and starts the animation. If a target element is passed as argument, the spinner is added as first child and horizontally and vertically centered.

var opts = {
  lines: 13, // The number of lines to draw
  length: 20, // The length of each line
  width: 10, // The line thickness
  radius: 30, // The radius of the inner circle
  corners: 1, // Corner roundness (0..1)
  rotate: 0, // The rotation offset
  direction: 1, // 1: clockwise, -1: counterclockwise
  color: '#000', // #rgb or #rrggbb or array of colors
  speed: 1, // Rounds per second
  trail: 60, // Afterglow percentage
  shadow: false, // Whether to render a shadow
  hwaccel: false, // Whether to use hardware acceleration
  className: 'spinner', // The CSS class to assign to the spinner
  zIndex: 2e9, // The z-index (defaults to 2000000000)
  top: '50%', // Top position relative to parent
  left: '50%' // Left position relative to parent
var target = document.getElementById('foo');
var spinner = new Spinner(opts).spin(target);
