Personalize blog entry

Hi

I have this blog entry and sience the last update it shows other blog entries at the bottom. but with no style at all. I was wondering if theres a way to improve the design of that area. Also i have a slider with quotes, but the buttons to navigate it are aligned to the left, and i havent been able to center them.

Here’s an image to explain what i just said https://imgur.com/Y65Fl6v and the link to my web page where i need to make changes https://www.fluocardent.com/asi-nos-ven/

Thanks in advance
