Subtract from an integer using jquery

I want to subtract 50 from the offset of a div.
My code is this.

if (scroll) {
    $('html, body').animate({"scrollTop":  $(scroll).offset().top - 50});
        $(scroll).css('color', 'blue');
        $(scroll).mouseleave(function() {
        $(this).css('color', 'black');
        });
    }

But this isn’t working. Can someone help me ?

Answer 1

You can use css method to change the top property

$('div').css('top', $('div').offset().top - 50);​

Demo.

Update:

$('div').animate({'top' : $('div').offset().top - 50});

Also make sure if (scroll) evaluates true.
