Blog page shows white boxs

Hello,
I can’t figure out how to change on my “news” page that has white background in each of the blog post, and can’t space it from my top bar. Too close. Also on the “event” page which is just a link to a category, the header not transparent like the rest of the site and has white background to some circle on it’s left.
