BG Image doesn't show up initially. Only after resizing the browser window, the BG image shows source code: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Persoonlijke website van Huub, Monique en Nick</title> <style> img.bg { /* Set rules to fill background */ min-height: 100%; min-width: 1024px; /* Set up proportionate scaling */ width: 100%; height: auto; /* Set up positioning */ position: fixed; top: 0; left: 0; } @media screen and (max-width: 1024px){ img.bg { left: 50%; margin-left: -512px; } } #page-wrap { position: relative; width: 400px; margin: 100px auto; padding: 40px; background: white; -moz-box-shadow: 0 0 20px black; -webkit-box-shadow: 0 0 20px black; box-shadow: 0 0 20px black; } p { font: 15px/2 Arial, Sans-serif; margin: 20 20 20 20; text-indent: 0px; ALIGN="center"; } </style> </head> <body> <img src="intro.jpg" class="bg"> <div id="page-wrap"> <p ALIGN="center"><b>Persoonlijke website van Huub, Monique en Nick<b></p> <p ALIGN="center"><img src="under-construction.jpg" border="1px"</p> </div> </body> </html>

Not all platforms will enable compositing for fixed.
