"CSS Pages" vs "Flash Pages" terminology?

Hello! I’m an “old noob” getting back into web design after a few years out of it. I was looking at the Kool Sites forum, and noticed the “CSS galleries” sticky at the top, as if its some kind of special category.

Terminology question- are what ascii-based pages of content that used to be called “HTML pages” now more commonly called “CSS pages”? (because of the proliferation of CSS for layout)

There also seems to be a division between “CSS pages” and “Flash pages” …anyone have any thoughts on where the blurs between these 2 might be? (it’s more of a high-level question, I guess)
