How to reduce the white space at the top of the webpage

Hi @sakin, Hope you're well. I have a problem - that probably has an easy fix?? www.crestchic .fr - When you take a look at this page there's a lot of white space at the top of the screen (logo area/header right sidebar area etc). How do I reduce that white space. The old test site www.marcomsonline. co.uk was much better (and more aligned) and I haven't done anything different (that I know of) when I transferred the website between domains. Please help :) Regards Neil
