How do you style your font family names that contain whitespace? To quote or not to quote. The answer is available at WC3.
“Font family 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.”
So, if you do not put quote marks around a font family name that contains whitespaces, you may end up with an incorrect font name like “TimesNewRoman” instead of “Times New Roman”. Here is the correct way to style a font family with whitespace in the name:
.class-name
{
font-family : Georgia, "Times New Roman", serif;
}
