2016 theme header

Hi,

First post and first week on www.remarpro.com after moving from .com

I would like to just move my header on my site to the top and the menu sit underneath it. I can’t seem to find the code to do this in my theme and don’t have enough coding experience to do it myself.

my site is https://www.fitforpurposegolf.com

I understand about child themes but want to just update this one thing until I decide on getting a template designed to use.

Thanks in advance.

Stephen
