This module competes with the Bricks module for Bootstrap. A little bit less flexible, but more settings for the layout. It works with Bootstrap 4 themes like Breeze. This theme adds some nice CSS to the module.
Default you can choose between these paragraph types. (you can add types yourself eg for adding a video field)
You can nest the types. Here i have a tab with a carousel with 2 images.
