Customize viewer css. pygments.css not found

[drglenn]

Using the Developer tools, I see the particular file above is in a sandbox and only shows up in the binary libraries.

$ grep -rie pygments
Binary file lib/calibre-extensions/python-lib.bypy.frozen matches
Binary file lib/libcalibre-launcher.so matches

The issue is with a book on programming where the examples are shown as if they are quote. It is not displaying the actual example text in the theme I'm using in KDE (kubuntu 20.04).

With Chrome as my default browser I can use the the tools to view the code and highlight each section a particular <div> is displayed in the viewer. I can adjust the code easily enough by:

<span style="color: blue;">
  code example text
</span>

But I don't have any idea where I could apply the change to this particular book.

Thank y'all in advance.

PS: I've scanned the docs, but can't claim to have read it and see any information on customizing a individual books CSS. So shoot me if it exists and just give the section I need to look in pretty please. (Ah, did I mention I'm a wee bit lazy?)

pygments is used by calibre for syntax highlighting, and has nothing to do with book styling. If you want to edit the css for a book, use the edit book tool.

I found it in poking around the ebook reader. Right clicked on the page, then preferences and changing the page theme to White was the answer to the problem. Previous to this the page looked like the attachment
