Can't Change Font Size or Font Family

[paddle-to-the-sea]

I have been trying to use the style.css file to change the font size and/or font family. I have tried the following:

• changing the file ferret-master/share/style.css pre-compilation from 10px to 18px.
• changing the file /usr/local/share/ferret/style.css after compilation and installation from 10px to 18px.
• changing the font-family in both files to serif and monaco.

None of the above has worked so far. Ferret always displays a sans-serif font that is relatively small (apparently matching the GtkTextView { font-family: sans; font-size: 10px; } of the original style.css file.

I'm running Devuan GNU/Linux 4.0 Chimaera (which is based off of Debian 11 Bullseye).

In any event, thank you for this neat little program.
