Thumbnail hover effect

I am trying to add an image hover effect to a page thumbnail.
When hovering on the thumbnail a larger preview of the thumbnail displays. The hover effect is similar to a tooltip effect. How can i achieve this hover effect with the Sydney theme.

Hello @pase,

It looks like this issue requires some coding and testing, this goes beyond our support policy. It’s considered advanced customization. As an option, you can find a reputable freelancer on Upwork for this kind of service.

Kind Regards, Roman.
