#string-no-newline

Disallow (unescaped) newlines in strings.

禁止在字符串中使用（非转义的）换行符。

a {
  content: "first
    second";     ↑
}                ↑
/**              ↑
 * The newline here */

The spec says this: "A string cannot directly contain a newline. To include a newline in a string, use an escape representing the line feed character in ISO-10646 (U+000A), such as "\A" or "\00000a"." And also: "It is possible to break strings over several lines, for aesthetic or other reasons, but in such a case the newline itself has to be escaped with a backslash (\)."

w3 标准上说：“一个字符串不能直接包含换行符。为了在字符串中包含一个换行符，用一个转义代表ISO-10646 (U+000A) 中换行字符。如"\A" 或 "\00000a"”。还有:“为了审美或其他原因，字符串可以多次换行，但在这种情况下，换行符本身必须使用一个一个反斜杠(\)进行转义。”
