Thread:Project:Support desk/Can I change the font size of the page title?

Thanks for your great help. I've been wondering if I could find a way to change the font size, partially, of the page title. For example, can I make the title "MediaWiki (Wikipedia)" like as "MediaWiki (Wikipedia) " or "MediaWiki (Wikipedia)" (I got this one! It can be done by the "Italic title prefixed" template.) ? I'm so curious about this. Wating for you great guys' answer.
