Syntax highlighting styles in inline code missing background color

[lukasz-r]

Pandoc doesn't apply full syntax highlighting styles for inline code. In particular, the background in inline code does not change. This makes inline code reading a bit difficult since it doesn't stand out from the surrounding text.

The problem didn't exist in older Pandoc versions. I'm getting this issue with 3.7.0.2 version, but can't pinpoint the exact version when the problem occured first since I've had quite a long break using Pandoc.

Here's the code:

+ let's see here: `man git`{.bash}

	+ and here:

	```bash
		man git
	```

Pandoc run for HTML:

pandoc -f markdown+backtick_code_blocks+fenced_code_attributes+inline_code_attributes -ps --highlight-style=espresso -o out.html in.md

Result: inline code is not on dark background, as opposed to code blocks:

I'm attaching the input file (MRE/MWE) and Makefile for easy testing.

Details:

Pandoc 3.7.0.2
openSUSE Tumbleweed
Kernel: 6.16.3-1

in.md

Makefile:

file_in := in.md
file_out_html := out.html
file_out_pdf := out.pdf

all : out.html out.pdf

pandoc_run = pandoc -f markdown+backtick_code_blocks+fenced_code_attributes+inline_code_attributes -p $(1) --highlight-style=espresso -o $@ $<

$(file_out_html) : $(file_in)
	$(call pandoc_run,-s)
$(file_out_pdf) : $(file_in)
	$(pandoc_run)

.PHONY : clean
clean :
	$(RM) $(file_out_html) $(file_out_pdf)

We just need the right CSS for this, I think.
In the CSS pandoc provides, code blocks get background colors through a rule like this:

    div.sourceCode
      { color: #bdae9d; background-color: #2a211c; }

Not clear how to do the same for inline code.
Adding

    code.sourceCode { color: #bdae9d; background-color: #2a211c; }

gives us

which is not bad.

See also jgm/pandoc#7223 for PDF. There may be special problems for PDF/LaTeX.

Thanks for a quick reply!

The solution works well, I'm getting the desired result with e.g.

code.sourceCode {
	color: white;
	background-color: black;
}

in the CSS style file. This keeps same colors for code blocks and inline code.

I'll move this to skylighing because that's the place it would need to be addressed.
