Base64 背景图像多行？

是否可以放base64背景图像是多行而不是一长行？如果是这样，怎么办？

我当前的主体 CSS 是：

body {
  background-color:  #FFFFFF;
  background-image:  url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAICAIAAABLbSncAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAAAZSURBVBhXY/iABP4jAQYqSiCbi2wsA/UkAIeAuaFCb0TzAAAAAElFTkSuQmCC);
  background-repeat: repeat;
  height: 100%;
}

将代码放在引号之间，并在换行之前添加反斜杠。

body {
    background-color:  #FFFFFF;
    background-image:  url('data:image/png;base64,iVBORw0KGgoAAAANSUhEUg\
    AAAAgAAAAICAIAAABLbSncAAAAAXNSR0IArs4c6QAAAARnQ\
    U1BAACxjwv8YQUAAAAJcEhZcwAADs\
    MAAA7DAcdvqGQAAAAZSURBVBhXY/iABP4j\
    AQYqSiCbi2wsA/UkAIeAuaFCb0TzAAAAAElFTkSuQmCC');
    background-repeat: repeat;
    height: 100%;
}
