Scrolling to the top in Custombox modal

Question

I'm using Custombox to open a modal. This modal however can get a little long so I added a "Go To Top" button.

I found this at SO and I've been trying different combinations to make the modal scroll back up.

I've tried:

$("html, body").animate({
    scrollTop: $("#modal-id").offset().top
}, 800);

and a handful of different combinations for getting the offset but I can't get it to scroll to the top of the modal.

Where is the scrollbar? (on the browser window, or on the modal window) — Michael Oakley, Apr 04 '16 at 18:46
@ameenulla0007 Really? When the modal becomes a bit longer, the vertical scrollbar is there and I can manually scroll using my wheel mouse. — dokgu, Apr 04 '16 at 18:49
Is there a jsfiddle we could look at? It looks like the plugin disables the scrollbar on the page. https://github.com/dixso/custombox/blob/master/src/css/custombox.css#L6 — Michael Oakley, Apr 04 '16 at 18:55

The scrollbar belongs to the .custombox-modal-wrapper element, so you should scroll it, not <body> or <html>:

$(".custombox-modal-wrapper").animate({
    scrollTop: $("#modal-id").offset().top
}, 800);

Hey, this worked! When I tried using a different element I used the `.custombox-modal-container` `div` and it didn't work. How do I determine which element has the scrollbar? – dokgu Apr 04 '16 at 18:59
@PatrickGregorio I just inspected the gray background in Chrome DevTools and found out it's this element. – Michał Perłakowski Apr 04 '16 at 19:02
Both the `.custombox-overlay` and the `.custombox-modal-wrapper` highlight the scroll bar when I inspect those elements. – dokgu Apr 04 '16 at 19:02
@PatrickGregorio But `.custombox-overlay` isn't a parent of the `.text` div (div which contains actual content of the modal), it doesn't have any children at all. – Michał Perłakowski Apr 04 '16 at 19:05
