Came here thinking I would learn something, but this is mainly a post to sell your content (which is totally fine, and I am already checking out your youtube channel)
I will say this, After "coding" front-end development for 4 years I do agree that StackOverflow is a blessing in disguise. The best is to really research down to the core of what you are using to actually proactively learn what you are doing.
Also, The height is set to 200px, not 100px ;)
Fixed the CodePen, thanks! Also, while I did use this to link off to some of my other stuff (glad you're enjoying my videos!), I do think it's an important kick in the pants for some people who complain that CSS isn't intuitive, or who struggle with it for whatever reason (and this is both for new people, and people coming from JS or other languages).
That said, I don't want to come off as too sale-sy either, so I'll try to include more info in future stuff!
Same could be said for JS or any "programming" language, as long as you don't really study the language / syntax, you will struggle with it in the future
