In my browser(opera), my background image takes up the full height off the screen, but on my friends(firefox) there appears a large black banner beneath it (black because that is the bgcolor)
I give you the css hopefully you guys can help me.
body { color:#C00; background-color:#000; background-image:url('../background.jpg'); background-repeat:no-repeat; background-position:top; height:100%; }
this will make your background image to fill the available space of the document, in Opera Safari and IE5.5 and up...,but I can't help you with firefox. You'll need to hack it.
html, body {
height: 100%; Width: 100%;
margin: 0; padding: 0; border: 0;
background-image: url(background.png);
background-repeat: no-repeat;
background-size: 100% 100%;
-o-background-size: 100% 100%;
-webkit-background-size: 100%;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='background.png',sizingMethod='scale');
}
