native.showWebPopup( ) - How to get the same scale on different resolutions?

Hello!

My app runs at 320 x 480 resolution (letterboxed) on Android.
I am showing a native.showWebPopup( ) on the full screen.
The website shown has a size of 320px as well. I want it to be filling from side to side
on all devices/resolutions. However, for example in the Samsung S3 simulator the website is just a small area in the middle of the Popup.

Is there a possibility to get it shown at full size on all devices?

The website is like:
[html]


body {
background-color: #ffffff;
color: #666;
font-family: "Lucida Grande", "Lucida Sans", "Lucida Unicode", Helvetica, Arial, Sans-Serif;
font-size: 18px;
padding: 5px;
text-align: center;
}
html { -webkit-text-size-adjust: none; }
[...]

[…]

Thank you in advance!
