How to embed showclix script code?

We are trying to use this piece of script code on our site

<script id="EventsWidgetScript" type="text/javascript" src="https://www.`showclix`.com/js/events_widget.js">
</script>

I am using the Embed Content Block. it works fine on desktop/laptop displays but gets very wonky on phones. The biggest problem is that as you advance in the embedded app, it advances to a weird spot, keeps moving lower and lower.

You can test it at these temp page, one with text and images and one with nothing but the embedded code:https://www.intothedarksf.com/showclix-tix3
