Hmmm, ok that’s strange as the header pattern has it’s own css class – #header_pattern using that code should affect the entire header. I’ve tested on mine and it’s working so it must be something else in your site which is stopping the header moving up.

Can you please set up an admin level log in for us, email it through to http://www.redfactory.nl/contact-us/ for my attention and we’ll log in and try out some css overrides to see what’s happening for you.
