I can't find a function to raise the line slightly above the bottom footnotes. I would be very happy to hear from you (with a skinshot or a link to a video tutorial if possible).
See Type > Document Footnote Options... > Layout
at the bottom - "Offset"
That's not how it works. When you interact with this function, the distance between the footnotes at the bottom changes as well. You can see it in the video.
All I wanted was to raise the line 2-3 millimeters up.
Is there anything else you can do?
I didn't see if you tried "offset" (at the very bottom of the Footnote Options window) - here I have it set to 24 pt (2p0):
I may be misunderstanding your question, though.... ?
Thank You, I saw where it was.
