# string-no-newline
|
|
|
|
Disallow (unescaped) newlines in strings.
|
|
|
|
```css
|
|
a {
|
|
content: "first
|
|
second"; ↑
|
|
} ↑
|
|
/** ↑
|
|
* The newline here */
|
|
```
|
|
|
|
[The spec](https://www.w3.org/TR/CSS2/syndata.html#strings) 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 (\)."
