If you specify the same name on each `details` element they behave like an accordion automatically [1], no need for JavaScript. If you set one of them to open that one will be initially open.

It's not about using it as an accordion, it's about controlling the open/closed state from other interactions.

different things with the same name? O_O

It’s the name of the accordion and matches how radio buttons work. If you want to distinguish them, you’ll give them different ids.

I understand it, just wondering if it is good taste.

On a different note, trying to use an accordion this simplistic is quite terrible.

Not very nice.
