Header, full width

Hi there,
I would be very glad if you could help me:
I`m wondering if its possible to extend the header (the font of the navigation) to the edge of the monitor.
regards & thanks in advance!
Katharina

Dear Katharina,

Could you please try to apply the following CSS code?

.header-wrap .container{
  width: 100%;
}

Kharis

Thanks you for your help!
