Fonts and Epub - What works on Sony, Works for Pocket Pro too!
Replace DATA/FONT with abook/fonts and put the fonts in the "fonts" folder on the SD card. To use bold, add the following:
Code:
body {
font-family: "Freestyle Script";
font-weight: bold;
}
Note that you need to add the bold variant of the font as a font face for this to work as you would expect.
