I came across a post today while I was trying to subscript something: How do i superscript text?
I found a different approach that doesn’t require markup based on this article: Unicode subscripts and superscripts - Wikipedia
TL;DR: while you can’t easily apply the markup that generates subscripts and superscripts, you can easily get the unicode character for a given, common, superscript or subscript and use that. It’s displaying fine in my existing webflow project.
Anyway, figured I would share the wealth, since I didn’t find any results that didn’t involve a lot of styles futzing.
