Header image appears cut off on mobile

Hello,

I am fine tuning my website https://www.3innyc.com and I am having trouble with the site’s header getting cut off when it is displayed via mobile. I’m wondering if this is a margin setting in my CSS or something else that I can address.

I notice that when I view the site on my iphone or ipad that the left most part of the screen displays further to the right than it should. It’s like it is cutting off the left most part of the header image so the blog post title doesn’t line up with the rectangle image box of the header.

Any guidance would be appreciated.

Thanks,

Kelly
