Is there a way to make only the rhombus image respond to hover events? I want to exclude the transparent area, as shown in this picture.
<img src='http://s30.postimg.org/xpd6gwla9/1_Copy.jpg' id="first">
#first:hover {
-moz-box-shadow: 3px 3px 5px 6px #ccc;
-webkit-box-shadow: 3px 3px 5px 6px #ccc;
box-shadow: 3px 3px 5px 6px #ccc;
}
