Scrolling in Modal makes background scroll on Safari

Question

I need to have some help with an annoying thing. I have an modal popup which has vertical scrollsbar inside. When scrolling inside the modal sometimes the background scrolls instead. I have tried to add

body{
position:relative;
overflow: hidden;
}

which works fine on most of the browsers, but Safari for my iPhone still scrolls!

Please help me find how to solve this!

Regards Kristian

Answer 1

$('body').css('overflow','hidden');
$('body').css('position','fixed');

Did it for me.
