Thanks for writing in and sorry you are experiencing the issue. Would you mind pointing us to the exact location of the issue. We checked your videos page and thumbnails looked fine on desktop and mobile. The videos resize automatically.

Hope this helps – thanks!

Thank you.

Thanks for updating the thread! This is because the embed code is none responsive. Try the following workaround:

Enclose your YouTube Embed code within this structure:

<div class="videoWrapper">
    <!-- Copy & Paste embed code from YouTube Here-->
</div>

It should look like this:

<div class="videoWrapper">
    <iframe width="560" height="315" src="https://www.youtube.com/embed/kjK5kdP88CA" frameborder="0" allowfullscreen></iframe>
</div>

Then you need to add this under Custom > CSS in the Customizer or in your child theme’s style.css file.

.videoWrapper {
	position: relative;
	padding-bottom: 56.25%; /* 16:9 */
	padding-top: 25px;
	height: 0;
}
.videoWrapper iframe {
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}

Hope this helps – thanks!
