Plugin for featured images

Hi,

Apologies if I am using the wrong terminology. I am looking for a plugin the will let me display images on my homepage like the three images below the image slider on this website that I came across. https://www.beardbrand.com

I can seem to find anything like it most likely because I am not using the right words to search for it. So like you will see the images be joined without any gaps in between and be responsive.

Any help is welcome. Thank you.
