Hi centerprh
On our demo site, we use a custom html module in 'custom3' position, here is its content output:
<div class="gkTextBlock">
<h2>We build responsive,<br />mobile-friendly website</h2>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam scelerisque faucibus risus non iaculis. Fusce a augue ante, pellentesque pretium erat. Fusce in turpis in velit tempor pretium. Integer a leo libero.</p>
</div>
<img src="templates/gk_simplicity/images/demo/manufacturers.png" alt="Manufacturers" />
<img src="templates/gk_simplicity/images/demo/tablet_image.png" class="gkImageBlock" alt="Image block" />
and make sure that in 'Advanced' tab of this module, you add 'layered' class suffix: https://prnt.sc/ui5u23
I checked your site but there is no module in this position.
