Displaying Styles for specific IDs

First, this is my first post, so I want to say thanks for such a cool tool for web development. Really, big thanks to FCK.

Now, a question: Can FCKEditor be styled with specific ID-Tag combinations?

I want FCKEditor to display styles for a specific ID-tag combination because that's how I style the HTML sent to the browser.

EXAMPLE CSS
#Content h1 {
font-size: 18px;
}
#Content p {
font-size: 12px;
}

EXAMPLE HTML
<div id="Content">
<h1>Blah Blah Head Line</h1>
<p>A paragraph of great text saying nothing at all.</p>
</div>

Can FCKEditor be styled with these ID-Tag combinations?

My Results So Far

I put FCKEditor in a <div id="Content">, but it doesn't display the styles.

I have FCKEditor using my style sheet, but it only displays the H1 an P styles if they are alone like this.
p {
font-size: 12px;
}
h1 {
font-size: 18px;
}



BIG THANKS AGAIN FOR A COOL TOOL.
