`lch()` and `lab()` in `formatCss` has no `%` about culori

[ai]

Got it. I misread this part of migration guide.

Hi @ai, this was a breaking change included in the 3.0.0 release:

lab and lch serialize the L component as <number>, not <percentage>

This was included to align with the latest CSS Level 4 spec.

Culori 3.x should be able to parse L as <number> in lab() and lch(). Can you share a snippet so I can get a better idea?

Ah, maybe I should have included a note about that in the migration guide as well (it's only in the release notes), but I was not sure what change to suggest. Browsers and Culori will accept either format for lab() / lch() and for L the result is identical whether specified as number or percentage, since its range is [0, 100].
