Hi there,
you can try this.
Create a new Hook Element and select the hook you required for desktop position.
Add this HTML around your adsense code:
<div class="grid-container sticky-footer-element">
<!-- Adsense code here -->
</div>
And then this CSS:
.sticky-footer-element {
position: fixed;
bottom: 0;
left: 0;
right: 0;
z-index: 100;
background-color: #fff;
}
/* Add body bottom margin the height of sticky element */
@media(max-width: 768px) {
body {
margin-bottom: 100px;
}
}
