CSS1 7.1 (emphasis mine):

# A block starts with a left curly brace ({) and ends with the
# matching right curly brace (}). In between there may be any
# characters, except that parentheses (()), brackets ([]) and braces
# ({}) always occur in matching pairs and may be nested. Single (')
# and double quotes (") also occur in matching pairs, and characters
# between them are parsed as a string (see the tokenizer in appendix B
# for a definition of string).
#
# ...
#
# A declaration-block starts with a left curly brace ({) and ends with
# the MATCHING right curly brace (}).

The spec doesn't explicitly give an example with a block before a
colon, but I see no justification in the spec for ignoring the rules
given above on the left hand side of a declaration.
