<p>Modern, HTML5-compliant browsers automatically construct a <code><head></code> element if the tags are omitted in the markup. <a class="external" href="https://www.stevesouders.com/blog/2010/05/12/autohead-my-first-browserscope-user-test/">This behavior cannot be guaranteed in ancient browsers</a>.</p>
