Agreed.

Honestly the best thing I tell people to get some decent css basics is try to build a few stylus themes.

You can instantly see the results in devtools. I can't think of any other language that does that besides html, and even then you have to save and refresh.

Css is pretty easy to pick up in the chrome devtools at least because it has built in autocomplete. Showing you exactly what you can set the values too etc
