Hello, my main site ( victormatara.com) header is not showing AdSense in a proper way. It overlaps outside. I wonder what’s the problem considering the fact that the secondary website ( stavica.com) shows it pretty well.
you may want to try adding your advert code inside a grid-container wrapper like so:
<div class="grid-container">
<!-- your advert code goes here -->
</div>
This will limit the size of the advert to the width of your content.
But that is about the only thing the theme can do – the responsive behaviour and its sizing can only be controlled by the advert provider.
