<name>

The name of a font family.

<generic>

These keywords can be used as a general fallback mechanism when an author's desired font choices are not available. As keywords, they must not be quoted. Authors are encouraged to append a generic font family as a last alternative for improved robustness.

serif	Glyphs of serif fonts, as the term is used in CSS, have finishing strokes, flared or tapering ends, or have actual serifed endings (including slab serifs). Serif fonts are typically proportionately-spaced. They often display a greater variation between thick and thin strokes than fonts from the sans-serif generic font family. CSS uses the term ‘serif’ to apply to a font for any script, although other names may be more familiar for particular scripts, such as Mincho (Japanese), Sung, Song or Kai (Chinese), Batang (Korean). Any font that is so described may be used to represent the generic serif family.
sans-serif	Glyphs in sans-serif fonts, as the term is used in CSS, have stroke endings that are plain -- without any flaring, cross stroke, or other ornamentation. Sans-serif fonts are typically proportionately-spaced. They often have little variation between thick and thin strokes, compared to fonts from the serif family. CSS uses the term sans-serif to apply to a font for any script, although other names may be more familiar for particular scripts, such as Gothic (Japanese), Hei (Chinese), or Gulim (Korean). Any font that is so described may be used to represent the generic sans-serif family.
cursive	Glyphs in cursive fonts generally have either joining strokes or other cursive characteristics beyond those of italic typefaces. The glyphs are partially or completely connected, and the result looks more like handwritten pen or brush writing than printed letterwork. Some scripts, such as Arabic, are almost always cursive. CSS uses the term cursive to apply to a font for any script, although other names such as Chancery, Brush, Swing and Script are also used in font names.
fantasy	Fantasy fonts are primarily decorative fonts that contain playful representations of characters. These do not include Pi or Picture fonts which do not represent actual characters.
monospace	The sole criterion of a monospace font is that all glyphs have the same fixed width. This is often used to render samples of computer code.
