shouldn't be a synonym of .
Dynamic properties (CSS expressions) have more to do with JavaScript than CSS.

By the way how do you vote the reversal? Is it only available to moderators?

I never really understood why that one was synonymized... –  animuson Apr 29 '12 at 0:14
Probably because people don't understand the difference between the two. "Expressions" is a very generic term. –  Charles Apr 29 '12 at 1:44
@charles I guess the voting threshold (5+) is sometimes too low for popular tags. –  Knu Apr 29 '12 at 1:49

I removed the synonym. Unfortunately the two tags had been merged at some point, and there's no way to reverse that. The tag will have to be added manually to any question where it applies.

I tried to re-tag a question and it didn't work. And the tag still redirects to css. –  Knu Apr 29 '12 at 2:11
@Knu That's weird, you have plenty of reputation to create a new tag. Which question? Also, css-expressions is not redirecting for me. –  Bill the Lizard Apr 29 '12 at 2:14
I will use "css-expression" instead and then add the plural as a synonym. –  Knu Apr 29 '12 at 2:16
@Knu I just created css-expressions. See if you can use it now. –  Bill the Lizard Apr 29 '12 at 2:17
@Knu Can you see that the tag was created now, and that it no longer maps to css? Unfortunately I don't know much about how tag synonyms are implemented, so I don't know if this is a caching issue or what. Have you tried restarting your browser, or switching to FF? –  Bill the Lizard Apr 29 '12 at 2:24
You should try yourself: try to tag this question. edit: OK I have no idea how you did that: it's not working here. –  Knu Apr 29 '12 at 2:27
@Knu It seems to be working for me. –  Bill the Lizard Apr 29 '12 at 2:29
@Knu When I click on the css-expressions tag it doesn't go to the css page anymore, it goes to the page listing the two questions I retagged. Mod rights don't override synonym mappings. If I try to use a synonymized tag, it gets replaced. –  Bill the Lizard Apr 29 '12 at 2:36
It must be caching then. [css-expressions] still redirects me to [css]. –  sudo Apr 29 '12 at 2:37
@dennis you mean I am on a different server than Bill? –  Knu Apr 29 '12 at 2:40
@Knu: As far as my limited knowledge about these things goes, just a different CDN endpoint. If this is a caching issue, it should correct itself soonish. –  sudo Apr 29 '12 at 2:44
I just checked, and we now have both [css-expressions] and [css-expression]. Two distinct tags, neither synonyms of one another nor of [css]. Personally I'd go with [css-expressions] as Microsoft informally calls them (formally [dynamic-properties]), rather than the function name expression() itself... –  BoltClock's a Unicorn Apr 29 '12 at 3:14
(Also makes it consistent with the other [css-*] tags even though this one's non-standard, just because...) –  BoltClock's a Unicorn Apr 29 '12 at 3:21
@BoltClock'saUnicorn: Confirmed. It's effectively desynonymized. –  sudo Apr 29 '12 at 3:23
@Dennis: ... and I've gone ahead and synonymized them. stackoverflow.com/tags/css-expressions/synonyms –  BoltClock's a Unicorn Apr 29 '12 at 4:00
