Header

Hello team, I want to change the header in something like the simple header in the elevatebiz pro. But, if I want to change the header in elevatebiz, the result is as you can see at tien.woonzorgdashboards.nl. I should like to have the navigation more to the right side of the page; a kind of space between header and picture and the picture over the whole width of the page. Is there someone who can give me a suggestion. Thanks in advance Kind regards Hans Hagmeijer
