I have a background image centered that Chrome displays offset by one pixel.
CSS
#container {
background: url("images/header.jpg") no-repeat scroll 50% transparent;
width: 100%
}
#header {
width: 986px;
margin: 100px auto 0 auto;
}
HTML
<html>
<body>
<div id="container">
<div id="header">centered content</div>
</div>
</body>
</html>
I guess it has to do with how different browsers handle the center -or 50%– property of the background in CSS:

Is there a known (simple) hack or alternative method to fix this? Background container has to be 100% wide.
For me, this did the trick:
I will post the link for this solution as soon as I find were I got it from a few days ago.
In the same post, the guy said the problem was with odd or even number for container width.
Anyway, this fixed the problem in my case.
