Sounds great, I know a lot of people who could benefit from this.
I think CSS has historically been a lot harder than it was supposed to be, because browser support was shit. They were slow in adopting new CSS features, and existing features (even simple features!) weren't correctly implemented in all browsers (looking at you, Internet Explorer!).
Things are better now, for the most part, but everyone seems to have migrated to web frameworks, and writing HTML and CSS from scratch has become something of a dying skill.
