When exporting to PDF, is there a way to remove the grey background of code blocks?

I’m asking because I want to be able to print my notes and the grey background would waste ink/toner. Thank you.

I think you could try with Adobe Acrobat Pro (or DC or what they call it these days) or some other program.

You should be able to style it using CSS (for the light mode), like in the following:

Export to PDF code block is gray on slighty more gray with my preferred theme and gray on white with default

If you switch the Tomorrow Night Bright theme to light mode, you’ll see the same faint code block text. I think the theme is just not optimized for light mode (where PDF export gets its styling from). That said, adding !important results in the correct output in my test vault using Tomorrow Night Bright. !importants are generally considered bad form to use except in rare cases, but I think they are fine for a PDF export snippet. We don’t need to worry about other CSS interactions or conflicts;…

Where should I place the CSS code?

There are some guides floating around, but snippets go in the .obsidian/snippets folder, and then you enable them from the appearance settings.
