Why would font names need quotes?
conventions, css, fonts
Solution
You can always put a specific font family name in quotes, double or single, so `Arial`, `"Arial"`, and `'Arial'` are equivalent. Only the CSS-defined generic font family names like `sans-serif` must be written without quotes.
Contrary to popular belief, a font name consisting of space-separated names such as `Times New Roman` need not be quoted. However, the spec recommends “to quote font family names that contain white space, digits, or punctuation characters other than hyphens”
Problem
As far as I know, one needs to use double or single quotes for fonts if they contain spaces, like: ``` font-family: "Times New Roman", Times; font-family: 'Times New Roman', Times; ``` But on Google Fonts (http://www.google.com/webfont), I also see ``` font-family: 'Margarine', cursive; ``` Some even use it like so: ``` font-family: 'Margarine', 'Helvetica', arial; ``` I find this weird, as the following works as well: ``` font-family: Arial, Helvetica, sans-serif; font-family: Cambria, serif; ``` So what is the correct usage of quotes around font names in CSS?
