CSS3 Rotate Animation

Question

<img class="image" src="" alt="" width="120" height="120">

Cannot get this animated image to work, it is supposed to do a 360 degrees rotation.

I guess something's wrong with the CSS below, as it just stays still.

.image {
    float: left;
    margin: 0 auto;
    position: absolute;
    top: 50%;
    left: 50%;
    width: 120px;
    height: 120px;
    margin-top: -60px;
    margin-left: -60px;

    -webkit-animation-name: spin;
    -webkit-animation-duration: 4000ms;
    -webkit-animation-iteration-count: infinite;
    -webkit-animation-timing-function: linear;

    -moz-animation-name: spin;
    -moz-animation-duration: 4000ms;
    -moz-animation-iteration-count: infinite;
    -moz-animation-timing-function: linear;

    -ms-animation-name: spin;
    -ms-animation-duration: 4000ms;
    -ms-animation-iteration-count: infinite;
    -ms-animation-timing-function: linear;

    animation-name: spin;
    animation-duration: 4000ms;
    animation-iteration-count: infinite;
    animation-timing-function: linear;

    @-ms-keyframes spin { 
        from { 
            -ms-transform: rotate(0deg); 
        } to { 
            -ms-transform: rotate(360deg); 
        }
    }
    @-moz-keyframes spin { 
        from { 
            -moz-transform: rotate(0deg); 
        } to { 
            -moz-transform: rotate(360deg); 
        }
    }
    @-webkit-keyframes spin { 
        from { 
            -webkit-transform: rotate(0deg); 
        } to { 
            -webkit-transform: rotate(360deg); 
        }
    }
    @keyframes spin { 
        from { 
            transform: rotate(0deg); 
        } to { 
            transform: rotate(360deg); 
        }
    }
}
