Blog Background Color / Hiding Removing Author Icon

I would content area of my blog page:

https://www.asktheyogadiva.com/blog/

…to match my other pages:

https://www.asktheyogadiva.com/about/

I’m referring to the brown area… it’s missing from the blog page for some reason.

Also, I’d like to hide the author icon and title for each entry.

Thanks in advance!
