I’ve see an example at http://css-tricks.com/perfect-full-pa… of a jQuery method that should work but I’m having trouble implementing it. Is this even possible or am I wasting my time?
Here is some of their sample code:
jQuery Method
This whole idea becomes a lot easier (from a CSS perspective) if we know if the aspect ratio of the image (inline we intend to use as a background) is larger or smaller than the current aspect ratio of the browser window. If it is lower, than we can set only the width to 100% on the image and know it will fill both height and width. If it is higher, we can set only the height to 100% and know that it will fill both the height and width.
We have access to this information through JavaScript. As usual around here, I like to lean on jQuery.
#bg { position: fixed; top: 0; left: 0; }
.bgwidth { width: 100%; }
.bgheight { height: 100%; }
$(window).load(function() {
var theWindow = $(window),
bg = ("#bg"),
aspectRatio = $bg.width() / $bg.height();
function resizeBg() {
if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
$bg
.removeClass()
.addClass(‘bgheight’);
} else {
$bg
.removeClass()
.addClass(‘bgwidth’);
}
}
theWindow.resize(function() {
resizeBg();
}).trigger(“resize”);
});
This doesn’t account for centering, but you could definitely alter this to do that. Credits to Koen Haarbosch for the concept behind this idea.
Works in:
IE7+ (could probably get in IE6 with a fixed position shim)
Most any other desktop browser
