CSS3 - Transition on DOM Removal

Using keyframes, it is possible to animate an element as soon as it is inserted into the DOM. Here's some sample CSS:

@-moz-keyframes fadeIn {
    from {opacity:0;}
    to {opacity:1;}
}

@-webkit-keyframes fadeIn {
    from {opacity:0;}
    to {opacity:1;}
}

@keyframes fadeIn {
    from {opacity:0;}
    to {opacity:1;}
}

#box {
    -webkit-animation: fadeIn 500ms;
    -moz-animation: fadeIn 500ms;
    animation: fadeIn 500ms;
}

Is there some similar functionality available to apply an animation (via CSS, no JavaScript) to an element right before it is removed from the DOM? Below is a jsFiddle I made to play around with this idea; feel free to fork it if you know of a solution.
