Does anyone know the theme/plugin in use here?

Hi

I’m currently looking at a slight redesign of my website https://www.photoguides.net/
My main desire is to feature specific content and allow users to access certain guides with ease.
My inspiration is from this website here. https://www.visualphotoguide.com/
The featured post box in the center of that page is almost exactly what I’m looking for. It’s simple, interactive, user friendly and advertises certain guides.
Does anyone know the theme this person is using? Or is this featured box a plugin?
Or rather, can anyone help me add one of those boxes to my own website?

Thanks
