Re: [csswg-drafts] Proposal: Custom CSS Functions & Mixins (#9350)

The easiest thing to recognize here is that CSS has always had several spots for extension in terms of vendor prefixes like

- `:-{vendor}-{property}`
- `:-{vendor}-{pseudoclass}`
- `::-{vendor}-{pseudoelement}`
- `:-{vendor}-{function}( )`

Custom things in CSS are just "vendor prefixes without a vendor" so you wind up with `--`
