text changing on centered sentence

[PaulPoul]

Hi,

I have trouble using textillate on centered H1. i change between few different size's words and every time a new word appear, the sentence auto center again. I would prefer that the other part of the sentence don't move , just the words appear and disappear.

Maybe it's more understanable visitng the website, check the H1
