I need help. My reader displays all my converted ePub books in what looks like Times New Roman. I’d like them to be in Georgia font.
I’m starting with a RTF source file which is set to and displays in Georgia, in MS Word. I save the file as HTM, filtered.
Add it to Calibre, where it shows as a ZIP file, and then do the RTF to EPUB conversion
So far I’ve tried to apply bits and pieces of guidance from the Calibre user manual and various MR posts about changing fonts with no success. Here’s what I’ve done so far:
Created a folder (fonts) in the root of my PRS-600 directory. In my case it is M:\fonts.
Copied the Georgia ttf font files to said folder.
Added some script to the Preferences/Conversions/Look & Feel/Extra CSS pane, see below.
Performed the conversion (ZIP to EPUB)
I had expected the CSS addins to force the reader to display the books in Georgia font.
I have SIGIL, and can see the CSS code I added, but all I get is Times New Roman.
I’m fairly sure my lack of knowledge of HTML is a big part of the problem. What am I missing and/or doing wrong.
BTW. The Calibre viewer shows the fonts as intended, but the reader does not.

Extra CSS code:

@font-face {
font-family: "Georgia";
font-weight: normal;
font-style: normal;
src: url(res:///Data/fonts/georgia.ttf);
}

@font-face {
font-family: "Georgia";
font-weight: bold;
font-style: normal;
src: url(res:///Data/fonts/georgiab.ttf);
}

@font-face {
font-family: "Georgia";
font-weight: normal;
font-style: italic;
src: url(res:///Data/fonts/georgiai.ttf);
}

@font-face {
font-family: "Georgia";
font-weight: bold;
font-style: italic;
src: url(res:///Data/fonts/georgiaz.ttf);
}

body { font-family: "Georgia", serif; }
