</ul>
<h3>How it works technically (if you care)</h3>
<ul>
<li>Adds <code>loading="lazy"</code> to all <code><img></code> and <code><iframe></code> inside <code>the_content</code> and other areas.</li>
<li>Also wraps <code><img></code>, <code><iframe></code> and the content of <code><pictures></code> in <code><noscript></code>.</li>
<li>Adds the <a href="https://github.com/mfranzke/loading-attribute-polyfill" rel="nofollow ugc">loading-attribute-polyfill</a> to do its magic in JavaScript.</li>
</ul>
<p>Feedback/Help is very welcome.</p>
