The include method will not work in R markdown documents. Instead one should use, in a separate script, the write method to save the CSS file.
Linne$ new()$ rule( sel_tag("p"), color = "white", fontSize = 30 )$ write("style.css") # save
Then use that file in the front matter of the R markdown file, for instance.
output: revealjs::revealjs_presentation: css: style.css
