Parallax offset from top

[theedgy]

Hi there.
I noticed that you are calculating element height based on offsetTop value which is relative to closes parent. That means when i put your parallax image into some content wrapper in the middle of page height, then this calculations are based on that wrapper and not on window, so it ends up with half of image because of wrong calculations.

PS. As a reference i fixed it by myself for own purposes, but you can review and use it as well. It was about to change the line : https://github.com/marrio-h/universal-parallax/blob/master/dist/universal-parallax.js#L48
into var containerTop = document.documentElement.scrollTop + container.top

Works like a charm, thank you.

Hi,
I had an issue with sticky headers: the parallax backgrounds were shifted according to its parent element (the image wasn't covering the entire element). With this update, the issue is solved, thanks you!
