Shadow animation jQuery plugin

Bitstorm.org > jQuery plugins > Shadow animation

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).

Example

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

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