Searchable collapsed content with hidden=until-found

Limited support Reference ↗

hidden="until-found" collapses content while keeping it discoverable through Find in Page and fragment navigation. The browser reveals the matched section before scrolling to it.

<a href="#archive">Jump to the archive</a>

<section id="archive" hidden="until-found">
  <h2>Archive</h2>
  <p>Still searchable while collapsed.</p>
</section>

Support and assistive-technology behavior still vary. The element also keeps a layout box, and display: none, contents, or inline prevents automatic reveal.
