Logo is behind menu.

Hey guys.

I’m currently doing a website for a mate and he asked if it was possible to have the logo overlapping the menu just a little bit. Adding it through the theme he has didn’t make it possible, so I added the image into the header code, so it appears top left of the page.

However, when I add negative margins (so the menu moves up towards the image at the top), the menu goes over the image. If it was to simply go under the image, then all my issues would be solved!

I guess the menu needs to be told to go under the image, or the image needs to be sat on top of everything. I’m just not sure how to go about doing it.

Anyway, thank you all in advance for any advice. Cheers!

Sadly the site isn’t live at the moment, but hopefully I’ve given enough description 😀
