how to add a horizontal line in header?

Hey,

I wanna make a similar header like on the image. I kinda have a code to space the navigation and the logo to where I want, but how do I add a vertical line in the header? like here: https://superherodesign.wixsite.com/marketing

is it possible? 

Thanks,
