What is font-family?

In a font-family property, fonts are listed and separated by commas. They are specified as family-name or generic-name.

The family-name value indicates the font family, such as “Helvetica.”

By contrast, the generic-name value is a fallback font family when no other specified fonts can be used. It should be a keyword without quotations, such as ‘serif’ or ‘cursive’. It will specify the font’s finishing stroke, with serif having tapering ends and cursive having joining strokes.

When specifying font family names in CSS, they should be quoted as strings or unquoted with identifiers. Quoted font family names should contain white space, digits, or punctuation instead of hyphens.
