iOS (Safari and Chrome) black border around div

Question

I have this div with no border. On the iPhone/iPad browsers it appears with a black border around. The code:

.progress {
position: absolute;
left: 0px;
z-index: 9999;
background: #ffffff url(img/progress.gif) center 95px no-repeat;
height: 100%;
}

I already tried with:

border: 1px solid white;

But to no avail. Also transparent brings nothing.

Edit: Actually I am not sure what is happening. Since this div appears on other cases without border. Go to http://liebdich.biz/blanc to see it live. It is the Ajax "loading" animation div . Whenever you click on a link you can see it. However if you go to http://liebdich.biz/blanc/profile and click on an image you see the same div , but with a border...? Can it be, that this is in connection with the jQuery fadeOut of the images?

Thank you!!

This was happening to me and it had to do with the meta tag allowing zoom

Apparently iOS Safari has a problem with resizing things and creates that artifact

Applying a meta tag to disable zoom solved my problem (user-scalable = no)

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
