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

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "This question pertains only to a specific site in the Stack Exchange Network. Questions on Meta Stack Exchange should pertain to our network or software that drives it as a whole, within the guidelines defined in the help center. You should ask this question on the meta site where your concern originated." – CRABOLO, Martijn Pieters, Shadow Wizard, Aziz Shaikh, nicael
I removed the synonym. Unfortunately the two tags had been merged at some point, and there's no way to reverse that. The css-expressions tag will have to be added manually to any question where it applies.
