Support css variables/custom properties

[robbevp]

Hi there 👋

It would be great if emmet had built in support for custom properties / css variables.
I'm imagining something like c:v expanding to color: var(${1}), fz:v expanding to font-size: var(${1}) and so forth

I know I could add this in my own snippets.json, but AFAIK that would require me to add this for all css properties where I'd want to use this.

I'd be happy to give this a try - but currently wouldn't know where to start

In theory this should already be possible, see css.keywordAliases / css.keywords.

The problem is VScode, arguably the most popular implementation of emmet, doesn't support these features.
