This creates a page template giving you a blank page so only the content of the page is displayed. Header and footer are totally empty. This is great for page builders (Beaver Builder, Divi, etc), landing pages and squeeze pages.
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/B8V-b8RDjiU?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe> 
This plugin will load everything that is normally included in the wp_head() and wp_footer(), so all scripts and styles should load as normal.

Thank you!
