In xaringanthemer: Custom 'xaringan' CSS Themes

IN_PKGDOWN <- identical(Sys.getenv("IN_PKGDOWN"), "true")

First, add the xaringan-themer.css file to the YAML header of your xaringan slides.

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

Then, in a hidden chunk just after the knitr setup chunk, load xaringanthemer and try one of the [theme functions][theme-functions].

```r`r ""`
library(xaringanthemer)
style_mono_accent(
  base_color = "#1c5253",
  header_font_google = google_font("Josefin Sans"),
  text_font_google   = google_font("Montserrat", "300", "300i"),
  code_font_google   = google_font("Fira Mono")
)
```

Matching ggplot Themes

xaringanthemer even provides a [ggplot2] theme with theme_xaringan() that uses the colors and fonts from your slide theme. Built on the showtext package, and designed to work seamlessly with Google Fonts.

Color and fill scales are also provided for matching sequential color scales based on the primary color used in your slides. See ?scale_xaringan for more details.

More details and examples can be found in vignette("ggplot2-themes").

style_mono_accent(
  base_color = "#1c5253",
  header_font_google = google_font("Josefin Sans"),
  text_font_google   = google_font("Montserrat", "300", "300i"),
  code_font_google   = google_font("Fira Mono"),
  outfile = NULL
)

library(ggplot2)
ggplot(diamonds) +
  aes(cut, fill = cut) +
  geom_bar(show.legend = FALSE) +
  labs(
    x = "Cut",
    y = "Count",
    title = "A Fancy diamonds Plot"
  ) +
  theme_xaringan(background_color = "#FFFFFF") +
  scale_xaringan_fill_discrete()

cat("![](../reference/figures/index-theme_xaringan_demo-1.png)")
