How can I make a link in the reverse clickable div

Question

When the div “flips”, I would like to be able to click the link, how can I achieve this?

Apparently, I need to write some more text, or it will not allow me to post this question, who will drink later?

CSS

.flip-container {
    perspective: 1000;
}

.flip-container:hover .flipper, .flip-container.hover .flipper {
    transform: rotateY(180deg);
}

.flip-container, .front, .back {
    width: 320px;
    height: 200px;
}

.flipper {
    transition: 0.6s;
    transform-style: preserve-3d;
    position: relative;
}

.front, .back {
    backface-visibility: hidden;
    position: absolute;
    top: 0;
    left: 0;
}

.front {
    z-index: 2;
    background-color: red;
}

.back {
    transform: rotateY(180deg);
    background-color: green;
}

HTML:

<div class="flip-container" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
        <div class="front">
            <!-- front content -->
            Front
        </div>
        <div class="back">
            <!-- back content -->
            <a href="http://www.google.com">Click me</a>
        </div>
    </div>
</div>

Add the following to your code. Adding translateZmakes it interactive

Fiddle

.back {
    transform: rotateY(180deg) translateZ(1px);
    background-color: green;

}
