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...

  • Probably because people don't understand the difference between the two. "Expressions" is a very generic term.

  • @charles I guess the voting threshold (5+) is sometimes too low for popular tags.

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 That's weird, you have plenty of reputation to create a new tag. Which question? Also, css-expressions is not redirecting for me. Apr 29, 2012 at 2:14
  • I will use "css-expression" instead and then add the plural as a synonym.

  • @Knu I just created css-expressions. See if you can use it now. Apr 29, 2012 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? Apr 29, 2012 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 It seems to be working for me. Apr 29, 2012 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. Apr 29, 2012 at 2:36
  • It must be caching then. [css-expressions] still redirects me to [css].

  • @dennis you mean I am on a different server than Bill?

  • @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.

  • 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... Apr 29, 2012 at 3:14
  • (Also makes it consistent with the other [css-*] tags even though this one's non-standard, just because...) Apr 29, 2012 at 3:21
  • @BoltClock'saUnicorn: Confirmed. It's effectively desynonymized.
