Header/Footer and Content alignment Issue WordPress

Hello I am currently experiencing a problem with WordPress the header/footer and article content aligns left on mobile/tablet where it should be centred as when viewed on a desktop/laptop. The header is currently cut off and the footer with the content displayed from the left where it should be centred.

The URL is www.canonbody.com – if anyone knows a fix I would be greatly appreciative.

It is the 2010 Childs Theme running on WordPress.
