Center Header Image

I was wondering if anyone knows how to center my header in line with my blog. my website is https://www.seaofsavings.com and as you can see my header is slightly off and not inline with my posts. Below is my coding that is in my header php file. I would appreciate any help, I have tried other methods I see online however it doesnt move my header.
