Gap between nav background and header

HTML & CSS
1

Need to remove small space between the main nav and the header.

Where is this space coming from since I’m using

margin: 0 auto;

The problem is caused by the logo image hanging out of the header. Fix it with this:

#HEADER {
  overflow: hidden;
}

Thx! Fixed it.
