<string>

The <string> CSS data type represents a sequence of characters. Strings are used in numerous CSS properties, including content, font-family, and quotes.

Syntax

A string is composed of one or more Unicode characters surrounded by either double (") or single (') quotes.

Most characters can be represented literally. When escaped with a backslash, they can also be represented with their respective Unicode code points in hexadecimal. For example, \27 represents the single quote ('), and \A9 represents the copyright symbol (©).

Importantly, certain characters which would otherwise be invalid can be escaped with a backslash (\). These include double quotes when used inside a double-quoted string, single quotes when used inside a single-quoted string, and the backslash itself.

New lines are invalid unless escaped with a line feed character such as \A or \00000A. In your code, however, strings can span multiple lines, in which case each new line must be escaped with a "\" as the last character of the line.

Examples

/* Simple quote escaping */
"Awesome string with double quotes"
"Awesome string with \" escaped double quotes"
'Awesome string with single quotes'
"Awesome string with \' escaped single quotes"

/* New line in a string */
"Awesome string with \Aline break"

/* String spanning over two lines (these two strings are exactly the same) */
"A really long \
awesome string"
"A really long awesome string"
