Menu
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.
