On page 58 (Ch. 3), I see an example of CSS:

h1 .special {
styles go here...
}

I typed in the following code:

<h1 class="special">Hello There</h1>

But it didn't work.

h1.special { } seemed to work, but not a space separator.

What did I do wrong?

Revision: Okay, I think I figured this one out. It's inheritance.
Question: would there ever be any elements that are within a header element? A <span>?
Or is h2 .special a bad example whereas p .special would make more sense?

Ya your fired query is absolutely perfect but there might be some site issues or you might be lacking somewhere as you need to check it out for commas and brackets.
