@amxmln it’s not a time thing, but a precedence thing. The cascade (origin, specificity, layers, etc.) determines which styles are applied. A feature of the cascade is that active transitions take precedence over everything else. Essentially it’s telling something “take forever to get to your destination even if your destination is really high priority.”
@noleli @amxmln Ah, but Amadeus has a point: In order to have a transition, it's not enough to have multiple styles competing in the cascade. There has to be an initial time when those styles didn't apply.
Unless you use the new @ starting-style rule, but I don't think that's well supported yet.
