background header

Hello Skandha, Sorry I have to bother you for a last time: Ion the website Laura.hagmeijer.nl there is a little white line under the primary menu. If I scroll down with the mouse, also above the primary menu there is a white space. I tried to add several css codes but the white lines under and above the primary menu stay. Is there a solution for this issue. If not we have to live with it. Kind regards Hans Hagmeijer
