Ask HN: Feedback on my first product to help beginners learn Bootstrap 4?

My journey started about a year ago after using Bootstrap 3 at work and on personal projects. I really liked the framework but had some difficulty learning the workflow and understanding some of the terminology. So I first set out to help others learn the component class names by creating a class reference and cheat sheet.

After this, I began thinking about other ways to help people learn and decided to create an educational product. I interviewed some of my designer/developer friends, performed on-page surveys, and emailed some of my subscribers. Overall it has taken me a year to create this and am excited to share it.

I am just starting to get the word out and was wondering if you would be willing to review what I created and provide any feedback. I would really value your opinion. Thank you!
