If I understand you correctly you can do this with CSS (using #). It has allready been discussed here:
view post 482513. Search for first accurance of "#" character as it's a long thread.
or in short... put on some TD or DIV in one container an ID="something" and then in CSS use something like this:
.title{
...something...
}
#something .title{
...something differnet...
}
Now use this container in some page and also use other, regular one (without ID="something") on the same page - you'll find out they have different style for titles! You can do same for .Normal class or any other class ofcourse.
Now you can put ID in container or somewhere above Pane so styles of modules can change after moving from pane to pane! Many interesting things can be done this way.
I hope this is what you searched for.
