Easily animate box shadows

With this jQuery plugin, you can extend the animate function to support the CSS box shadow property. You can animate the color, the x and y offset, the blur-radius and spread radius. Mark Carver contributed code to support rgba colors (the alpha channel) and Jason Redding contributed code to support multiple shadows.


Change the shadow to a centered 30 pixel blur with the color blue (#44f):

$('#box1').animate({boxShadow: '0 0 30px #44f'});

Just upload this file to your server and include it in your HTML below jQuery. Don't link to these files on this domain directly.


The easiest way is to use a content delivery network. Just paste the following code in your HTML just below jQuery.

<script src="//"></script>


To install the whole package, you can use one of the following commands:

git clone

npm install jquery-shadow-animation

bower install jquery-shadow-animation


The plugin works in the recent versions of Firefox, Safari, Chrome, Opera and Internet Explorer 9+.

Currently, the shadow offset, blur and spread should be defined in pixels, so no ems, percentages etcetera. jQuery should be at least version 1.8.
