I'm out of touch, I guess. Can I just use any tags with ordinary HTML? Is it correct HTML?

  You can use any tag name with a hyphen, IIRC.

  Yes, though I personally don't use it, a weird fear of colliding with obscure existing or new tags down the line. But technically, name spacing them with a prefix should cover that.

  Yep. The standard promises that new standard tags will never contain a dash, so if your custom tag does contain a dash, it can’t ever clash with future new browser features.

  The "data" prefix, followed by whatever you want, has been formalised for quite some time. The DOM provides a "dataset" property.

    That's for attributes, not tags, no?
    • beardyw 2y ago
      Yes, attributes. The property is on the element.
