Hi,
The default editor of Joomla often strips HTML tags when you add content for article or custom HTML module. This happens in CTA module on your site.
You can go to Global Configuration > Site Settings > Default Editor > set to None and add this output for module:
<div class="cta">
<a href="https://joomlart.com" title="Call to Action" class="btn btn-success btn-lg btn-block">
<span class="hidden-xs">Free Ground Shipping on All Us Orders Over $75</span>
<span class="visible-xs">* Free Shipping</span>
</a>
</div>
Regards
