Hi Jack,
The exam tested many subjects in the W3C CSS2 spec, but I have a
feeling the question was poorly worded. I think they were trying to
test using strings in CSS rules:
http://www.w3.org/TR/CSS21/syndata.html#strings
The spec says:
"It is possible to break strings over several lines, for esthetic or
other reasons, but in such a case the newline itself has to be escaped
with a backslash (\). For instance, the following two selectors are
exactly the same:
Example(s):
a[title="a not s\
o very long title"] {/*...*/}
a[title="a not so very long title"] {/*...*/}"
Otherwise, I agree with you on your other points.
