That is accurate--if those rules exist; but in the example given, no such
rules exist.

I don't think that's what he means. The first cascading rule sez:

"If no declarations apply, the inherited value is used. If there is no
inherited value (this is the case for the 'HTML' element and for properties
that do not inherit), the initial value is used."

In this case, there *are* declarations that apply. So the inherited value
would *not* be used.

What do you mean by "conflict"? Yes, it is accurate that blue != red.
However, the inheritance rules resolve this. As I have stated and given
evidence for (from section 1.3 of the CSS1 spec), inheritance is the default
behavior for color, and will be overridden by a specific value given on an
element which would otherwise inherit.

Oh, no? I find that very surprising. How about

	P { color: red }
	BODY { color: blue }

Are you telling me that P text in the document with this style sheet should
be rendered in blue?

This is different. Here, we have two rules which have the same weight. So
this is resolved by their order, according to the 5th cascading rule:

"Sort by order specified: if two rules have the same weight, the latter
specified wins. Rules in imported style sheets are considered to be before
any rules in the style sheet itself."
