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:
            
- 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); }
- In the CSS, specify where this font is used. To set it as default for
                  h1elements, use thefont-familyrule, as in the following example:h1 { font-size:20pt; margin-bottom:20px; font-weight: bold; font-family: "MyFont"; text-align: center; }
- Open the Configure Transformation Scenario(s) dialog box, select the DocBook EPUB transformation scenario, and click Edit.
- In the Parameters tab, set the
                  epub.embedded.fontsparameter tofonts/MyFont.otf. If you need to provide more files, use commas to separate their file paths.NoteThehtml.stylesheetparameter allows you to include a custom CSS in the output EPUB.
- Run the transformation scenario.
