Adding class to article

When I create an article, I can add a class to the article (top box)
This never shows up in my code however. That seems a bit strange to me, why be able to add it, if it does not show.

Only when I add classes to the elements they show up.

How can I make the article inherit the style to all the elements?

Hey,
It does show.... input testintroclass,testtintroid in the article header.
Now view source of your page in your browser....

Code:

---

<div class="mod_article testintroclass block" id="testtintroid" style="margin-top:5px; margin-bottom:5px;">

---

which is a div that wraps all elements.

Ohh yes... I see!
I did not look properly I guess...

Thanks
