“css-discuss is primarily intended to be a place for authors to discuss real-world uses of CSS. This doesn’t preclude discussions of theory, or nifty cutting-edge tricks that show off the power of CSS, or even talking about (X)HTML, DOM, and so forth. However, it’s greatly appreciated if such discussions have some practical payoff, even if it’s just teaching other list members a little bit more about how CSS works. While we don’t forbid discussions of the future direction of CSS, the W3C runs a listserv explicitly for that purpose called www-style. It’s probably a better place for those kinds of discussions.”
