`fig_caption`	... Arguments to be passed to `rmarkdown::html_document()` (`...` not including `toc`, and `theme`).
`table_css`	`TRUE` to load gitbook's default CSS for tables. Choose `FALSE` to unload and use customized CSS (for exmaple, bootstrap) via the `css` option. Default is `TRUE`.
`number_sections`	... Arguments to be passed to `rmarkdown::html_document()` (`...` not including `toc`, and `theme`).
`split_by`	character. デフォルト: 'chapter'. 'chapter', 'chapter+number', 'section', 'section+number', 'rmd', 'none' から選ぶ. ページを区切る単位.
`self_contained`	... Arguments to be passed to `rmarkdown::html_document()` (`...` not including `toc`, and `theme`).
`split_bib`	Whether to split the bibliography onto separate pages where the citations are actually used.
`template`	Pandoc template to use for rendering. Pass `"default"` to use the bookdown default template; pass a path to use a custom template. The default template should be sufficient for most use cases. In case you want to develop a custom template, we highly recommend to start from the default template: https://github.com/rstudio/bookdown/blob/master/inst/templates/gitbook.html.
`config`	A list of configuration options for the gitbook style, such as the font/theme settings.
`lib_dir`	... Arguments to be passed to `rmarkdown::html_document()` (`...` not including `toc`, and `theme`).
`pandoc_args`	... Arguments to be passed to `rmarkdown::html_document()` (`...` not including `toc`, and `theme`).
`...`	Other arguments to be passed to `base_format`. For `html_book()` and `tufte_html_book()`, `...` is passed to `html_chapters()`.
`config:`	list. デフォルト: 実際に出力して確認したほうが早い. 詳しくは bookdown のマニュアル.
`dev:`	character. デフォルト: `png` しかし将来 `ragg_png` にするかもしれない.
`code_rownumber:`	logical. デフォルト: TRUE. 行番号を表示するかどうか
