Boilerplate template for a theme iframe endpoint

<?php
/**
 * Template Name: Content Only
 * @package WordPress
 */
/*
This template can be used as a way to only show your events information without any template styling, which
could come in useful if you were embedding an iframe on another site and displaying events that way.

You could add specific styling just for this page by modifying the code below.

To install, insert the whole contents of this snippet onto a new file such as "content-only-template.php" and add the file to your theme folder.

To use, create a page on your WordPress site, and select the template 'Content Only'. Add whatever content you want to the page such as EM shortcodes, and view the page.
