Default CSS auto-completions don’t support function arguments completions in general, currently.
Not that I am aware of, with regards to shipped completions plugin (CSS/css_completions.py).
What you’ve seen in ST3 are variables such as --pb-heigth being picked up from buffer and suggested as so called word completions. Several heuristics with regards to which tokens are extracted have changed in ST4. It appears leading -- is causing those tokens from being ignored by those new heuristics as - is matched as word separator.
It’s because most/all? features in ST ignore word_separators setting.
