什么时候CSSfont-family值应该使用引号？[重复]-WhenshouldCSSfont-familyvalueusequotes?[duplicate]

You only need quotes when the font itself has a space such as "Times New Roman".

当字体本身具有诸如“Times New Roman”之类的空格时，您只需要引号。

Arial does not need quotes, but some people use quotes such as "Arial" to be more consistent. It is simply personal preference.

Arial不需要引号，但有些人使用诸如“Arial”之类的引号更加一致。这只是个人偏好。

Seen in Justin's below comment: font-family: times new roman; works without spaces (jsFiddle).

见于贾斯汀的评论：font-family：times new roman;没有空格（jsFiddle）。

You can call your new @font-face using font-family: 'entypo'; as you would normally expect. (link)

您可以使用font-family调用新的@ font-face：'entypo';正如你通常所期望的那样。 （链接）

Just going to answer from this:

To avoid mistakes in escaping, it is recommended to quote font family names that contain white space, digits, or punctuation characters other than hyphens:

为避免转义错误，建议引用包含除连字符以外的空格，数字或标点字符的字体系列名称：

body { font-family: "New Century Schoolbook", serif }

body {font-family：“New Century Schoolbook”，serif}

Font family names that happen to be the same as a keyword value ('inherit', 'serif', 'sans-serif', 'monospace', 'fantasy', and 'cursive') must be quoted to prevent confusion with the keywords with the same names.

必须引用与关键字值（'inherit'，'serif'，'sans-serif'，'monospace'，'fantasy'和'cursive'）相同的字体系列名称，以防止与关键字混淆同名。

By the CSS 2.1 spec, a font name needs to be in quotes if it contains characters other than identifier characters (which is a broader concept than just “Ascii letters and digits”) and spaces. So font-family: foo bar is correct, and so is e.g. font-family: entypo of course.

根据CSS 2.1规范，如果字体名称包含除标识符字符以外的字符（这是一个比“Ascii字母和数字”更广泛的概念）和空格，则需要在引号中。所以font-family：foo bar是正确的，例如font-family：当然是entypo。

Coding style is a different issue. It is always correct to quote a specific font family name (as opposite to generic names like sans-serif), so font-family: "entypo" is correct, too.

编码风格是一个不同的问题。引用特定的字体系列名称（与sans-serif这样的通用名称相反）总是正确的，所以font-family：“entypo”也是正确的。

Very theoretically, a font name also needs to be quoted if a specific font family name coincides with a generic name (I don’t think anyone ever created such a font) or if its name contains leading or trailing spaces or consecutive spaces (but no one in his sense would name his font that way).

在理论上，如果特定字体系列名称与通用名称一致（我认为没有人创建过这样的字体）或者其名称包含前导或尾随空格或连续空格（但没有），则还需要引用字体名称在他看来，一个人会用这种方式命名他的字体）。
