What module is used on this website?

Hi everyone,

I am currently building a website using WordPress and I need your help. You see, I am building a news portal and I’d like it to be similar to the one you see on this page: https://thebucampus.ca/

Can anyone tell me how he succeeded to divide his website into categories and to give it this shape because that is exactly what I want and need. What modules do I need?

Cheers,
