It's great your joining the WP club. I'm a little familiar with generatepress. It's a good tool just not my style. To developerish to me. I see they have a free grid. Kadence has their post grid in the Pro blocks. But it's easily super customizable without code. Also I've got a new course for beginners ru-vid.com/group/PLKQvvvjYDpgtgXvmFNwgIBTWx7OZt3y9a
