-        <img alt="" class="example-page-example-icon" src="../../../images/pattern-feed.svg">
-        <p>
-          <strong>NOTE:</strong> The feed role was introduced by WAI-ARIA 1.1.
-          Since native desktop operating systems offer only a few conventions that are applicable to the feed pattern, the implementation of a feed illustrated by this example is intended to serve as as a proposal.
-          Feedback is welcome in <a href="https://github.com/w3c/aria-practices/issues/565">issue 565.</a>

-        <p>
-          The example below implements the <a href="../feed-pattern.html">Feed Pattern</a> for a restaurant review site.
-          To imitate an infinitely scrolling set of data, information about ten restaurants is repeatedly loaded as the user reads the feed.
-          This example includes an article load time selector that simulates data fetch delays.

-        <p id="feed-controls-desc">
-          The following article loading delay time selector enables simulation of different amounts of latency introduced by data fetches.
-          Such latency can affect assistive technology behavior when using assistive technology functions for navigating by article.
