<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 (').
/* 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"
