Have you done a repo for this tutorial, Chris?

This is the code you want at a very base level for flexbox. However, you do have other options such as grid which involves less code.

.flex {
  display: flex;
  flex-wrap: wrap;
}

.flex-child {
  flex: 0 0 100%;
}

@media only screen and (min-width: 640px) {
 .flex-child {
    flex: 1;
  } 
}

This repo is an updated version of Ryan Bates screencast for Rails 5. I've used it on a project and it's great but the model had no associations so I'm not sure if it would work for nested resources
