What you are wanting is the use of a css class. With a css class you can do
different things on the same page. Here is a snippet of the css fiel for my
site http://www.barvin.com that shows a couple of classes:

a {color: #000000; font-family: Arial; font-weight: normal; font-size: 12pt;
text-decoration:underline}
.mnu {color: #000080; font-family: Arial; font-weight: normal; font-size:
10pt; text-decoration:none}
.top {color: #000080; font-family: Arial; font-weight: normal; font-size:
10pt}

Now since Publisher is writing it's own css based on your formatting of the
publication I would recommend that you use FrontPage if you are wanting to do
a lot with your own code and css implementations.

If you need more help with CSS and it's use I suggest you reference any CSS
topic web site for that assistance as that would get OT for this forum.
