Change pagetitle css

Hi,
I know my question could sound easy, but I can't figure out how to do what I want.

I would like to standardize the pagetitle of my categories the same way the "Latest news" appear on the frontpage. I know how to do it for module but not for the title of the categories.

Is there an easy way to do it?

Thank you in advance

Hi
Can you give us url to your site, please

Here is the frontpage with the titles like I want :: http://www.portailsi.com/

This is my test page (the one that I would like to set the title like the frontpage) :: http://www.portailsi.com/gouvernance/se ... ation.html

Thank you

Just to clarify, the title of the frontpage that I would like is the title "À la une" and in the second link, the title is "Sensibilisation".

Thank you
