在 bookdown 书中包含 css？

Question

我想包括以下内容 .css 以使我的书更宽：

.book .book-body .page-wrapper .page-inner {
    max-width: 1200px !important;
}

这是我的 .yml:

delete_merged_file: true
rmd_files: ["index.Rmd", "creating.Rmd", "subset.Rmd", "manipulation.Rmd",
"single_range_methods.Rmd", "intersection.Rmd", "overlap.Rmd", "join.Rmd",
"nearest.Rmd", "coverage.Rmd", "runlengths.Rmd", "runlength_dict.Rmd"]
output_dir: "."

bookdown::gitbook:
  css: css.css

这是我用来制作本书的 R 代码：

mpl = reticulate::import("matplotlib")
mpl$use('TkAgg')

library(reticulate)

use_python("/mnt/work/me/software/anaconda/bin/python")

library(bookdown)

render_book("bookdown::gitbook")

为什么我的书没有变宽？我做错了什么？

Answer 1

删除 css: 前面的缩进，并确保文件 css.css 与 index.Rmd 文件位于同一位置。

YML 应如下所示：

delete_merged_file: true
rmd_files: ["index.Rmd", "creating.Rmd", "subset.Rmd", "manipulation.Rmd",
"single_range_methods.Rmd", "intersection.Rmd", "overlap.Rmd", "join.Rmd",
"nearest.Rmd", "coverage.Rmd", "runlengths.Rmd", "runlength_dict.Rmd"]
output_dir: "."

output: 
  bookdown::gitbook:
css: css.css
