# R markdown

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
