- <!-- Need to set [adding-custom-css] -->
-
- [google-fonts]: https://fonts.google.com
-
- Yihui picked out great fonts for the [default xaringan theme](https://slides.yihui.name/xaringan/), but sometimes you want something new and interesting.
-
- **xaringanthemer** makes it easy to use [Google Fonts][google-fonts] in your presentations (well, as long as you have an internet connection) or to fully specify your font files.
-
- To use [Google Fonts][google-fonts], set the `_font_google` theme arguments --
- ```{r results='asis', echo=FALSE}
- cat(paste0("`", tvv[grepl("_font_google$", tvv)], "`", collapse = ", "))
- ```
- --- using the `google_font()` helper.
- See `?google_font` for more info.
-
- ```r
- mono_light(
- header_font_google = google_font("Josefin Slab", "600"),
- text_font_google = google_font("Work Sans", "300", "300i"),
- code_font_google = google_font("IBM Plex Mono")
- )
- ```
-
- If you set an `xxx_font_google` theme arguments, then `xxx_font_family`, `xxx_font_weight` and `xxx_font_url` are overwritten -- where `xxx` in `{header, text, code}`.
- Of course, you can manually set `header_font_url`, etc., and ignore the `header_font_google` argument.
-
- For example, suppose you want to use a ligature font for the code font, such as [Fira Code](https://github.com/yihui/xaringan/issues/83).
- Just set `code_font_family` and `code_font_url`!
-
- ```r
- solarized_dark(
- code_font_family = "Fira Code",
- code_font_url = "https://cdn.rawgit.com/tonsky/FiraCode/1.204/distr/fira_code.css"
- )
- ```
-
- If you need to import additional fonts for use in [custom CSS definitions][adding-custom-css], you can use the `extra_fonts` argument to pass a list of URLs or `google_font()`s.
-
- ```r
- mono_light(
- extra_fonts = list(google_font("Sofia")),
- extra_css = list(".title-slide h2" = list("font-family" = "Sofia"))
- )
- ```
