PDF: Modify the default template with a custom template

[AnsMelanie]

I have a DocFX project for which I need to provide a PDF version of the documentation.
So far, I’ve successfully generated the website, and the “Download PDF” button appears and works correctly. I also managed to add a header, footer, and cover page.

However, I’m struggling to modify the font family and the page margins of the PDF content. From what I understand, DocFX applies a default template, and customizing these elements requires creating a custom template to override the default one.

I’ve tried setting up a custom template, but I can’t get it to work properly, even after following the tutorial.

Does anyone have an example project where PDF customization (fonts, margins, etc.) is working successfully that they could share?
