DocBook to EPUB Transformation

The EPUB specification recommends the use of OpenType fonts (recognized by their .otf file extension) when possible. To use a specific font, follow these steps:
  1. Declare it in your CSS file, as in the following example:
    @font-face {
font-family: "MyFont";
font-weight: bold;
font-style: normal;
src: url(fonts/MyFont.otf);
}
  2. In the CSS, specify where this font is used. To set it as default for h1 elements, use the font-family rule, as in the following example: 
    h1 {
font-size:20pt;
margin-bottom:20px;
font-weight: bold;
font-family: "MyFont";
text-align: center;
}
  3. In your DocBook to EPUB transformation, set the epub.embedded.fonts parameter to fonts/MyFont.otf. If you need to provide more files, use commas to separate their file paths.
Note: The html.stylesheet parameter allows you to include a custom CSS in the output EPUB.
