These days, CSS usually refers to CSS2+. So, I suggest to map to .

I tried it myself...:

Suggest a css synonym: css2  Suggest   Failed to propose synonym: Version specific synonyms can only be created by moderators (click on this box to dismiss)

    But then how can you use [css2] to indicate that you are not asking about css3? Apr 16 '12 at 11:31

    I actually think this is a good idea. css2 doesn't mean anything useful on Stack Overflow. It's usually (ab)used to mean "I need this to work in older browsers such as IE7". However, IE7 supports even some CSS3, for example ~ and overflow-y. There are currently 61 questions tagged css2, and I think it could be removed from every question. Only this question arguably needs it, but the question still makes perfect sense without it.

I'm not sure this is a good idea. We have the tag to talk about the general field of .NET, as well as version-specific tags (such as ) for items that are specific (or more likely, introduced) in that specific version.

The tags are no different. There are times when you are speaking about CSS in general (or, the version that is most prevalent/widely-adopted at the time), but there are times when you want to speak about a specific version; this situation is when something isn't fully baked/just released so you can differentiate the technologies when an influx of new questions are going to come in on that new technology.

Going back and removing the version-specific tags (you're suggesting that is version one and that it be merged into version two) generally isn't a good idea. If anything, there might be people still using the old technology (depending on what we're talking about), and still need to differentiate between the two.
