Hi Matt,
Thanks for reaching out!
I also wasn’t able to make it work on my development website. I am not quite sure why it is not working but I have a workaround on this scenario.
Add the image source in the Navigation Label, see the example below.
<img src="/wp-content/uploads/2021/05/q-logo-2.png" class="hover-show">Sample Page
As you can see, I added hover-show class name in the image because that selector is usable to play around with CSS.
Then, please add this CSS code in your Pro > Theme Options > CSS.
.hover-show {
visibility: hidden;
}
.x-menu li a:hover .hover-show {
visibility: visible;
}
Please note that custom CSS code is outside the scope of our support. Issues that might arise from the use of custom CSS code and further enhancements should be directed to a third-party developer or you can avail One where we can answer questions outside of the features of our theme.
Hope that helps.
Thank you.
