I have a CSS sprite like:
HTML
<a id="estates" href="http://www.domain.com/estate"></a>
CSS
#estates {background-position: -200px 0px;width: 96px;height: 90px;}
#estates {background: url("http://www.domain.com/images/sprite.png") no-repeat scroll 0% 0% transparent;float: left;margin: 22px -2px 30px 33px;}
I would like when the user hovers over the link to change the image color to black and white or perhaps overlay a transparent png if that cannot happen?
