Centering post content, profile/poster info on top of post?

Is it possible (using CSS or something) to place the content of all posts in the center of the 'post' with the profile/poster information going on top? Similar to this website

(NOTICE: this example is NOT a forumotion site but is actually the sister site to my forumotion forum. I am trying to simply make it look similar. I figured showing this site would be the best way to convey my question.) Check any post on that site and you will better understand what I mean by posting content in the middle and poster info on top. Thanks in advance.

Would something like this be O.K.?
It's done on PhpBB2

We could center the post part also.

That is actually what I am looking for, though there is no need to center the post part. It looks good as it is. However, I am running phpBB3 and am not willing to convert to another version so is this possible to utilize with phpBB3 without overly screwing up the theme?

I'm sorry, I watched only the topic before that wants the same thing and uses phpBB2. I did it through templates, really can think of a way to do it with CSS.

It has been several days and no one else has bothered to attempt to help me.

So bump.

It seems to be a bit hard to find coding help on here.
