When I export a document as a continuous vertical scroll, I don't want any scaling. If the content is narrower than the window, it doesn't center in the window. Instead it seems to have some sort of padding of the background on the left side. This is fine until I wanted to add a fixed position element at the top of the page. My options for alignment of that are left or center. Neither one aligns with the rest of the document unless the window width is reduced.
These images are a screenshot of the width of my browser window with the fixed element centered then left-aligned. Fixed element is the white box at the top (with logo blurred).
I'd like to either mimic the padding that the document has on the left, or to properly center the document content on the page. Can you help?
