I have a problem with my background image. In normal view it´s fine, but when I scroll the view to smaller (e.g. 80% or less), there is white space on the bottom of the page (the background image is not covering the whole viewport).
I searched, tried various changes, but nothing worked. How can I fix this?

Now I exported my code and opened it in my browser, and there it works! However, in the codepen.io the same code doesn´t work (the white space is there). How can I understand this?? And is there a way to fix it even in codepen?
Thank you for your advice.
EDIT: I see another difference in the browser x in codepen: in the browser the calculator sticks to the top and in codepen there is a margin! How comes?
