Superscript/Footnotes?

Hey all -

Trying to work a way to display some essays and such. Found a good way to layout text to my liking for it, however, when it comes to add footnotes, I can’t find a way to make them superscript. Is this currently possible?

Currently my thinking is that I would take the 1, or whatever, make a span around it, give it a custom class that puts it into superscript and then link it to an anchor in a blockquote at the bottom. However I can’t find a way to make text in a span a link. (Additionally, I’m also considering taking the footnote and adding the related text into a tooltip - however, this becomes a problem when it’s a link. I’m looking for a solution if anybody has some ideas)
