How to make the Newspaper theme full width in post?


I have recently installed the theme on my website. However, my website is based on books review. Therefore, I like my posts to be on full-width so profiles, blog posts, videos, and everything else that the website contains will be easily visible and friendly accessible. I’ve tried to create the file full-width and paste it onto the theme folder but it still missing out and I can’t see the template article. It’s stuck on the Default theme. How can I fix that?

Best wishes,
