How do I use an iFrame for my header in WordPress twenty seventeen?

This is possible, but it’s not a best practice. Animations are cool, but iframes add complications and slow down the page load speed.

If you want to see what it looks like, edit this file:

../wp-content/themes/twentyseventeen/template-parts/header/header-image.php

And change the custom header div to this:

<div class="custom-header">

    <iframe scrolling="no" width="100%" height="1000px" src="http://robinseggstudio.com/homePage_12-5c/RobinSketch/"></iframe>

</div><!-- .custom-header -->
