It was another site. I'm sorry that I havn't responded earlier. I've been busy making budget for the house I live in.
The page was baby.gjesager.dk
It was because we changed the concept, and don't want a transparent header anymore.
I found out that by changing things in the CSS, from white to transparent I got some effect. When the header is transparent the sidebar is shorter than the content.
So my wife changed her mind and the header is no longer transparent. So I just need to adjust the side paddings.
Thank you very much for being here even though I were not.
