I have reviewed quite a few demos and have no idea why I can't get the CSS3 spin to function. I am using the latest stable release of Chrome.
The fiddle: http://jsfiddle.net/9Ryvs/1/
div {
margin: 20px;
width: 100px;
height: 100px;
background: #f00;
-webkit-animation-name: spin;
-webkit-animation-duration: 40000ms;
-webkit-animation-iteration-count: infinite;
-webkit-animation-timing-function: linear;
-moz-animation-name: spin;
-moz-animation-duration: 40000ms;
-moz-animation-iteration-count: infinite;
-moz-animation-timing-function: linear;
-ms-animation-name: spin;
-ms-animation-duration: 40000ms;
-ms-animation-iteration-count: infinite;
-ms-animation-timing-function: linear;
-o-transition: rotate(3600deg);
}
<div></div>
