Ah, that doesn't look so easy.

Maybe by examining the syntax group at the cursor position and checking
the part of the group name before the first uppercase letter? You would
of course need to have syntax highlighting enabled (and compiled-in).

See
:help synID()
:help synIDattr()
:help synIDtrans()

There are however places (such as in "ordinary" HTML text) where no
syntax group is defined, defaulting to the Normal highlight.

Also, in the value of a style= attribute within an HTML tag, the syntax
group is htmlString (highlight linked to Constant), not anything
CSS-related.


Best regards,
Tony.
