If you are converting a Vellum produced ebook, the body style consists of a font family declaration and then we add miscellaneous font family declarations elsewhere in the CSS. The font family lines below were from a single epub. The humourous part from my point of view is that none of these fonts were embedded in the epub.
Code:
body {
font-family: Palatino, Malabar, Merriweather, "Droid Serif", serif;
}
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
font-family: Baskerville, "Sorts Mill Goudy", Malabar, serif;
font-family:"Arial", sans-serif;
font-family: "Georgia", serif;
font-family:"Times New Roman", serif;
