Parameters in snippet call has no effect

It must have something to do with the CSS but don’t know where to look for the problem.What I don’t understand is that it works in the upload gallery and not on the page, but the CSS is working for the rest of the page. If I do a textlink on the page it has got the css formatting...

I got it to work now! It was still set as a container. When I have removed it everything works!
Thanx again!
