Thanks for the fast and qualified response. Now my block has the same style as the others, even using prosilver.

I used exact the code of the first posting.

Sorry: http://www.bilderschuppen.net/vestjylla ... hp?style=1

I´d add a left block according the first posting. Every thing is ok in style subsilver. But in style prosilver the backgroundcolor is lightblue #ECF1F3 instead of blue #CADCEB in the other left blocks. How can I change this?
