Full Width Header Logo on Pinboard Theme

Hi,

I’m fairly new to this and just setting up my first blog using the Pinboard theme. I am trying to get the header logo to take up the full width of the header with no white padding on the sides.

Does anyone know how to do this? I’m assuming I would need to enter some code somewhere.

My site is https://www.bedouindelights.com. You’ll see what I mean.

I would also like to have the social media logos on top of the image if this is possible.

Any tips?

Cheers!
