Value

The CSS styles are written to the file path provided in outfile (by default to xaringan-themer.css). If outfile is NULL, the CSS is returned directly as a character string.

Usage

To use the styles created by this theme function, make sure that you use xaringan-themer.css as your CSS file in your slides' YAML header. If you change the name of the output file using the outfile argument, use that name instead of the default file name.

output:
xaringan::moon_reader:
  css: xaringan-themer.css
