Iframe instead of background-image

Hi all,

how can i use an iframe as background instead of a background image? is that possible via phplugins? and if so, how?

Best regards
Oliver

This works for me.

function scripts() {
			echo <<<HTML

	<iframe
		src="https://picsum.photos/2048/2048"
		height="100%"
		width="100%"
		referrerpolicy="no-referrer"
		style="border: none; position: absolute; top: 0; right: 0; bottom: 0; left: 0; z-index: -1;"
		title="Iframe Example"
	></iframe>
	<style>
		.page, .main { background: transparent; }
	</style>

HTML;
// do not indent line above
	return false;
} // END /**/
