- VSCode Version: Code - Insiders 1.17.0-insider (f7962f0, 2017-09-20T05:24:33.599Z)
- OS Version: Windows_NT x64 10.0.15063
- Extensions: Extensions are disabled
Steps to Reproduce:
The grammar wrongly identify some at-rules as variables, causing wrong colorization for them.

Specifically, @charset, @keyframes, @page @namespace and @supports are not supported. (I have checked all at-rules on https://css-tricks.com/the-at-rules-of-css/, @document is not supported by the language service at all)
It's worse if I use the Monokai theme, because it doesn't support less variables so they are just white. (for real variables, maybe I need to open another issue)

Reproduces without extensions: Yes
