Css – webkit transform blocking link

csscss-transformscss-transitionswebkit

I've been working with transforms and transitions to create animated UI components without Javascript and really enjoying the results, but I've come across a disturbing issue that appears to be unique to webkit browsers.

On an element which I have rotated, an anchor that spans 100% of the width of the element is only accessible on the right 50% of the element.

This problem does not exist using -moz-transform in Firefox, but is 100% reproducible in both Chrome and Safari using -webkit-transform.

Here is the code:

<!doctype html>
<html>
<head>
<title>webkit spincard test bed</title>
<style type="text/css">
    #card-lists{
width:100%;
float:left;
}
#card-lists ul{
list-style:none;
}
#card-lists ul li{
width:230px;
height:236px;
}
.non-mobile #card-lists ul.card-list li .flipcard-container:hover .flipcard,
.non-mobile #card-lists ul.card-list li .flipcard-container.hover .flipcard{
    -moz-transform: rotateY(180deg);
    -webkit-transform: rotateY(180deg);
    -moz-transform-style: preserve-3d;
    -moz-transition: all 0s linear 0s;
    -webkit-transform-style: preserve-3d;
    -webkit-transition: all 0s linear 0s;
}
.non-mobile #card-lists ul.card-list li .flipcard{
    -moz-transform: rotateY(0deg);
    -moz-transition: all 0s linear 0s;
    -webkit-transform: rotateY(0deg);
    -webkit-transition: all 0s linear 0s;
    width:230px;
    height:236px;
}
.face {
    position: absolute;
    width: 100%;
    height: 100%;
    -moz-backface-visibility: hidden;
    -webkit-backface-visibility: hidden;
}
.face.back {
background-color: #125672;
    -moz-transform: rotateY(180deg);
    -webkit-transform: rotateY(180deg);
}
.face.front {
    background-color:#000;
}
</style>
</head>
<body class="non-mobile">
<div id="card-lists">
<ul class="card-list" id="cardes-list-total">
    <li>
    <div class="flipcard-container">
        <div class="flipcard">
            <div class="front face">
                <a href="#">
                <div style="width:100%; height:100%;">
                </div>
                </a>
            </div>
            <div class="back face">
                <a href="#">
                <div style="width:100%; height:100%;">
                </div>
                </a>
            </div>
        </div>
    </div>
    </li>
</ul>
</div>
</body>
</html>

Any help anyone could offer would be greatly appreciated as I've already spent an inordinate amount of time on the issue.

After combing through the webkit Bugzilla, I found someone who had the same issue and found a workaround.

.face.back {
    background-color: #125672;
    -moz-transform: rotateY(180deg);
    -webkit-transform: rotateY(180deg);
}

Becomes:

.face.back {
    background-color: #125672;
    -moz-transform: rotateY(180deg);
    -webkit-transform: rotateY(180deg) translateZ(1px);
}

The addition of the translateZ to the transform makes the left side of the element clickable.
