Theme is working whole page in ipad jquery mobile - ipad

Question

Hi
i am using theme="a", data-overlay-theme="a" and data-dismissible="false". But it is not working on whole page of iPad. How to apply on whole screen so that it look fine.
I also used this:
$(document).on('popupafteropen', '[data-role="popup"]', function(event, ui) {
$('body').css('overflow', 'hidden');
}).on('popupafterclose', '[data-role="popup"]', function(event, ui) {
$('body').css('overflow', 'auto');
});
Here is my code.
jquery css
.ui-popup-screen {
background-image: url(data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==); /* Necessary to set some form of background to ensure element is clickable in IE6/7. While legacy IE won't understand the data-URI'd image, it ensures no additional requests occur in all other browsers with little overhead. */
top: 0;
left: 0;
right: 0;
bottom: 1px;
position: absolute;
filter: Alpha(Opacity=0);
opacity: 0;
z-index: 1099;
}
.ui-popup-screen.in {
opacity: 0.5;
filter: Alpha(Opacity=50);
}
.ui-popup-screen.out {
opacity: 0;
filter: Alpha(Opacity=0);
}

This should help, overlay DIV should now cover whole page, doesn't matter how much screen size is big or is content scrolled or not.
CSS:
.ui-popup-screen {
position: absolute !important;
top: 0 !important;
right: 0 !important;
bottom: 0 !important;
left:0 !important;
}
This CSS block has been tested in jsFiddle example so I can be 100% sure it will work. If not We will find another solution.
