What is wrong with font-family: “Verdana, Arial, Helvetica”?
The quotes. This is actually a list with a single item containing the well-known ‘Verdana, Arial, Helvetica’ font family. It is probably intended to be a list of three items. Unlike in most other CSS1 properties, values for the font-family are separated by a comma to indicate that they are alternatives. Font names containing whitespace should be quoted. If quoting is omitted, any whitespace characters before and after the font name are ignored and any sequence of whitespace characters inside the font name is converted to a single space.
