HTML

              
                <details>
	<summary>explainer</summary>
<p>This is a quick and dirty example to accompany my blog post <a href="https://www.scottohara.me/blog/2022/02/05/dynamic-results.html">Considering dynamic search results and content</a>. Its primary purpose is to show how an accessible description can be added to a search field that dynamically renders results in the same page. Additionally, if you enter 5+ characters into the text field, an error message will appear saying there are no results.  Again, this is a very quick example.</p>
