<string>

Summary

The <string> CSS data type represents a string. It is formed by a Unicode characters delimited by either double (") or single (') quotes. A double quoted string cannot contain double quotes unless escaped using a backslash (\). The same practice applies for single quoted strings, they cannot contain single quotes unless escaped using a backslash (\). The backslash character must be escaped to be part of the string.

New lines are not accepted unless escaped by using a line feed character such as \A or \00000a. However, strings can span over several lines. In that case, the new line must be escaped using a \ as the last character of the line.

Characters can be described using their Unicode code point in hexadecimal, when escaped using \. \27 represents the single quote (').

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"
Note: Double quoted strings can also be escaped using \22 and single quoted strings can be escaped using \27.
