Change Blog Layout with CSS - Help Needed

Hi there,

I'm hoping to adjust the layout of my blog, but I can't find the option in the settings. It seems like I'll need to use CSS to make the changes.

I'm not very tech-savvy, so I was wondering if you could help me out. Currently, my blog displays one large post followed by two or four smaller posts. I'd like to change it so all the posts are the same (small) size.

For reference, here's my blog link: https://mylifejourney.altervista.org/

Thanks so much in advance for your assistance!

Very nice weblog I can see you managed to fix it already. May I ask which theme are you using for your blog?

The theme is called René by Altervista for WordPress
