How to position the post# links when visiting?

[Xarwin]

Hello everyone.

I recently finished my own custom theme for vBulletin but I'm stuck with something I can't find.
It's also a bit hard to explain but I'll try. Sorry if the title is a bit off but I couldn't think of how to describe it.

Basically I want to change the position the website loads after following/clicking a post link.

Example:
Clicking this link will get you to the post instantly. But how could I position exactly that? Like let's say, I want that it goes to the post + 1em added to the top for positioning. I used the official website as example, I'm using vBulletin 4.x myself.

Why am I asking
I have a banner which sticks to the top all the time.
This banner takes a part away of my posts when following the links. I want to fix this.
For example, this is what happens when going to a post: http://puu.sh/iFFJU/2cc9116444.jpg

Hopefully I can find an answer here, I didn't even knew how to ask this one lol.
Thanks in advance!
