\section{Usage}{
 To use the styles created by this theme function, make sure
that you use \code{xaringan-themer.css} as your CSS file in your slides' YAML
header. If you change the name of the output file using the \code{outfile}
argument, use that name instead of the default file name.\if{html}{\out{<div class="yaml">}}\preformatted{output:
xaringan::moon_reader:
  css: xaringan-themer.css
}\if{html}{\out{</div>}}
}

\examples{
# Create a xaringan style in a temporary file
xaringan_themer_css <- tempfile("xaringan-themer-", fileext = ".css")

style_xaringan(
  text_color = "#002b3",
  inverse_background_color = "#31b09e",
  inverse_text_color = "#002b3",
  outfile = xaringan_themer_css # omit in your slides to write the
                                # styles to xaringan-themer.css
