This code works like a charm to flip a div:
view
<div class="flip-container" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
        <div class="front">
            FLIP ME
        </div>
        <div class="back">
            FLIP ME AGAIN
        </div>
    </div>
css
/* entire container, keeps perspective */
.flip-container {
        perspective: 1000;
}
        /* flip the pane when hovered */
        .flip-container:hover .flipper, .flip-container.hover .flipper {
                transform: rotateY(180deg);
        }
.flip-container, .front, .back {
        width: 320px;
        height: 480px;
}
/* flip speed goes here */
.flipper {
        transition: 0.6s;
        transform-style: preserve-3d;
        position: relative;
}
/* hide back of pane during swap */
.front, .back {
        backface-visibility: hidden;
        position: absolute;
        top: 0;
        left: 0;
}
/* front pane, placed above back */
.front {
        z-index: 2;
        /* for firefox 31 */
        transform: rotateY(0deg);
}
/* back, initially hidden pane */
.back {
        transform: rotateY(180deg);
}
But it flips when I hover over the div. I would like for it to flip only when I click on it, and keep flipping once every time I click. There doesn't appear to be an :onclick method in CSS. Is there a way I can use jQuery to trigger the CSS above?
