Based on other replies, I believe they understood CSS well enough, but didn't understand the exact behaviour of the `group` class in Tailwind. Given neither of your comments seem to have made much sense given the context of the discussion, I wonder if you're just looking for confirmation of things you already 'know'.
EDIT: I'm sorry, I mixed you up with the other user who was replying criticising other people's CSS knowledge.
Baseline 2023 meaning all major browsers supported it in their latest versions sometime in 2023.. Like all new CSS stuff it's probably been a very long time coming. Everyone can't pay attention to everything though, regardless of their beard color.
No need to apologize, it just does not make sense to belittle other people's work when you lack the knowledge to judge it. Nobody told you it used JS for the effect, you conjured that up yourself.
