We're using Ghost as our blogging platform with deliberate constraints. Constraints aside, if you notice throughout the article, I'm using Codepen to help visualize the edits as I make them. This helps reinforce the concepts and is pretty low friction. I also provide the link at the end so readers can follow along. Thanks for reading!
