Hiding Newsmag Theme Sidebar On Mobile

Hi,
I am trying to hide my sites sidebar from appearing on mobile while using the Newsmag theme, can anyone give me any advice?

Hi

Please contact theme Author and let them know How to Contact your purchased theme Author (you can use comments to post your query in theme comments page), theme author will be happy to assist you if they have any such options in theme options settings. Otherwise you have to make it by custom coding.

Thanks
