How to delete the title bar ?

Hello,

I have a question from a client. He would like to delete entirely the title bar. He thinks that the fact the title in the menu is underdilned is enough to inform the visitor on which page he is.
I think it’s not a good idea. But the best way to convince hm is to show him the resullt. So is there a way to do this deletion easily in the code ?

Thnkas in advance,

Marianne
