Add extra css class to the output of code

[findmyway]

This will allow users to apply different css style to distinguish the input and output of code snippets, and maybe even add numbering to each code snippets.

I guess modifying

Franklin.jl/src/converter/latex/io.jl

Line 106 in 5eaac6e

reproc || return html_code(output)

a little would be enough?

Probably just adding a keyword argument to html_code should be enough; I’ll look into it, thanks for bringing this up! And if we want to add numbering to executable cells as well as output then we should also add a class to those, same process though, not very hard :)
