How to widen content area or entire site?

I want to widen my content area without sacrificing the sidebar, which is the exact width that I want it to be.

How can I do that with the Oxane theme?

This page (https://booksthathook.com/book-recommendations/) is a good example because the inframe is being cut off due to not enough space for content. The content area needs to be at least wide enough to accommodate the inframe.

Also, on my PC’s screen, the website has a lot of white space on both the right and left (about 3 inches on each side) so I think the entire site could be widened, but I don’t want to mess up how it appears on other devices.

Please help! Thank you. BTW, I know how to make a child theme, but my knowledge pretty much ends there. I can follow step-by-step instructions though if you tell me what to do ??
