CssLocation

Represents a location in a file or other source of data parsed by the CSS engine.

The @bytes and @line_bytes offsets are meant to be used to programmatically match data. The @lines and @line_chars offsets can be used for printing the location in a file.

Note that the @lines parameter starts from 0 and is increased whenever a CSS line break is encountered. (CSS defines the C character sequences "\r\n", "\r", "\n" and "\f" as newlines.) If your document uses different rules for line breaking, you might want run into problems here.
