How to add flip card animation with CSS keyframes?

Question

I built a blackjack game. Now I want the cards of the dealer, when they appear, to flip from back to the front. I built the keyframes in CSS but I can't apply it on the JS file.

JAVASCRIPT

function deal() {
    if (newgame == true) {
        var random = Math.floor((Math.random() * 13));
        var UserCards = document.getElementById('user');
        var card = document.createElement('img');
        card.setAttribute("width", 450);
        card.setAttribute("src", images[random]);
        UserCards.appendChild(card);
        UserCards.className ='myDIV';
        checkUserScore += cards[random];  
        if (checkUserScore > 21)
        {
            UserCards.appendChild(card);
            alert("you hit more than 21");
        }          
    }

EDIT: Did the OP leave out the function closing brace when pasting the code, or is that an actual error?

CSS

<style>
        .myDIV {
            margin: auto;
            border: 1px solid black;
            width: 500px;
            height: 500px;
            background-image:url(media/cards/UpsideDown.jpg);
            color: white;
            animation: mymove 5s infinite;
        }

        @keyframes mymove {
            50% {
                transform: rotate(360deg);
                background-image:url(media/cards/QC.jpg);
            }
        }
</style>

Please show your markup. Neither JS nor CSS mean anything without it. — isherwood
