Hello,
This markup shows my problem: Webkit browsers seem to create an erroneous width on floated parent elements with floated/overflow:hidden elements inside, when their width is set to 0. Is there a known workaround?
<!DOCTYPE html>
<html>
<head>
    <title>float & width</title>
    <style type="text/css">
        div {
            float: left;
            height: 50px;
        }
        div.section {
            background-color: green;
        }
        div.section div.content {
            background-color: red;
            overflow: hidden;
        }
        p {
            clear: both;
        }
    </style>
</head>
<body>
<p>width: 0 => Bug</p>
<div class="section">
    <div class="content" style="width: 0;">some content that should not affect the parent div's width.</div>
</div>
<p>width: 1px => good</p>
<div class="section">
    <div class="content" style="width: 1px;">some content that should not affect the parent div's width.</div>
</div>
</body>
</html>
