I've implemented the Supersize plugin on this page: http://www.olganaum.com/
I've tested the page on a few devices (Android, iPad2, desktop's Chrome), and everything would seem to be ok.
Yet on iPhone 5, when turn the device on landscape mode, this happens: http://i58.tinypic.com/20fexkk.jpg
As you might see, the image is not going full screen.
Any ideas?
If you're going through the same I went, then the key is on turning the device. It seems that when you turn from landscape to portrait and vice versa, the images or their container, for some reason, don't render full size again.
As I couldn't find the underlying reason, I applied this fix:
var rotationFix = function () {
jQuery(window).bind('orientationchange', function(e) {
document.location.reload(true);
});
}
Do notice this is just an easy exit, and every time you turn the device the page will refresh. If you want to take the solution a step farther, you may paint the containers to see which one is rendering full screen and which is not (and create a solution without refreshing the page).
