Is it possible to include text line numbering in Pressbooks, or has a theme been developed that has this feature? Think of line numbering for legal documents, which some word processors can do automatically.
We have a professor using both the online (self-hosted Pressbooks) version of a textbook and the print version of the same book in a class. The prof would like to see line numbering that he can use to guide discussion of pinpointed text for analysis, which would appear in both the online version and PDF exports.
Has this been done by anyone yet?
