Centering a div vertically & horizontally using jQuery

Question

I am using this script to center my div horizontally and vertically.

When the page loads the div gets centered vertically, not horizontally until I resize the brows

Related to your code snippet, you need to set the position first:

$(window).resize(function (){
    var $el = $('.className');
    $el.css('position', 'absolute').css({
        left: ($(window).width() - $el.width()) / 2,
        top: ($(window).height() - $el.height()) / 2
    });
});

Maybe you could set the position attribute via a static CSS style.
