Hi,
According to CSS 2.1 section 4.1.8, "Declarations and properties"
<http://www.w3.org/TR/CSS21/syndata.html#declaration> the semicolon is
used to separate multiple declarations for the same selector.
As the last declaration in a declaration block isn't followed by anything
from which it needs to be separated, it doesn't need the semicolon. In the
case of a declaration that is _not_ the last, it would be an error to omit
the semicolon.
Personally, I'd recommend including the semicolon every time. When
somebody goes to modify the stylesheet in the future and adds a
declaration at the end of the block, they may well not notice the lack of
it; as a result, not only would their new declaration not be applied, but
the formerly-last declaration would also suddenly stop working. It's
little things like this that can lead to hours of head-scratching :-(
Regards,
Nick.
