Use of aria-selected in CSS

[harry-gocity]

In the tab example, example styles us aria-selected: https://ariakit.org/components/tab

However it's not listed in https://ariakit.org/guide/styling#css-selectors.

I assume so, but is it safe to use?

Yes, it's safe to use for tabs. It's not mentioned in the styling docs because this attribute is not safe to use as a CSS selector in any other composite item, and that could cause confusion.

In the future, we may introduce a specific data-selected attribute that will be consistent across all composite items, but aria-selected will still work on tabs.
