[Theme: WP FanZone] Changing the CSS/Look of posts

Hey guys, running into some massive headaches trying to do edits that I’m pretty sure are straightforward but I can’t figure out.

Right now if you visit my page https://www.gametacularnews.com, the Home page and the Articles page display the same things.

So far so good, I used the Settings > Reading to send posts to a page other than just the Home Page.

Now to avoid redundancy in styling, I want the Articles page to display the posts one above the other, being also larger to fill the page at length (instead of having 2 posts side by side) while also removing the top dynamic post that goes through the page posts. Basically just want the white posts to be large and stack one above another.

This is so it doesn’t look cheap when navigating to another page that is meant to display all the same but in a more simplistic manner.

I’m pretty sure it’s just some CSS, but I don’t know at all how to start, how to reference the page specifically, the elements etc. Even trying to make sense of what I read in chrome’s dev feature I can’t find the ID’s. I need some kind of pointer on how to tackle this…

Any help is much appreciated!
