Remove sideblok from one style

[mp3president]

Hi there,

Got a question.
Is it possible to remove the side-block from one style only?
I have got a style dat is fixed and fluid that i use.
In the fluid, the side-blocks are perfect, but in fixed it smalls up my forum to much!

So maybe actually there are 2 questions.

1. How to remove the side-blocks in one style, so in the other one they are still there?
2. Maybe possible to maintain in the fixed style, and put blocks at right side without board will get smaller?

Hope someone can help me.
