<string>
The <string>
CSS data type represents a sequence of characters. Strings are used in numerous CSS properties, such as content
, font-family
, and quotes
.
Syntax
The <string>
data type is composed of any number of Unicode characters surrounded by either double ("
) or single ('
) quotes.
Most characters can be represented literally. All characters can also be represented with their respective Unicode code points in hexadecimal, in which case they are preceded by a backslash (\
). For example, \22
represents a double quote, \27
a single quote ('
), and \A9
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. For example, \\
will create a single backslash.
To output new lines, you must escape them 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.
However, to get new lines, you must also set the white-space
property to appropriate value.
Note: HTML entities (such as
or —
) cannot be used in a CSS <string>
.
