The `font-family` and `font` properties accept a list of generic font family names: `serif`, `sans-serif`, `cursive`, `fantasy` and `monospace`. If you wrap these generic family names in quotes, the browser will not interpret them as generic font family names, but will instead look for a font by that name (e.g. will look for a "sans-serif" font) -- which is almost never what you want.
