We just recently removed the hyperscript from these examples, so you rebase this to fix the merge conflict, we can merge it.

👍 Well done. https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-controls

Should www/content/examples/tabs-hateoas.md also be modified or not?

Thank you!

www/content/examples/tabs-hateoas.md appears to be working well, but I could change the IDs in this PR (tab-contents -> tab-content) to be consistent with the ones in that file.

Please let me know what would be the best course of action.

Not a big deal :)
