Remove Gallery Thumbnails

Good Afternoon,

I have been having a few issues trying to present a gallery without thumbnails. As an example, I would like the big image, without all the other images underneath, so that the viewer can simply click on a single image to bring up the lightbox and view as a slideshow, or scroll through the images that have been included in the gallery.

I found the following on a different thread, but it didn’t work – I placed it in the Quick CSS:

.avia-gallery-thumb {
display: none !important;
}

Among a variety of other different attempts, whenever I look at the page, whether after clearing the cache and restarting the browser, or otherwise – it simply continues to show the thumbnails. Is there additional CSS that must be included to achieve this?

I have Enfold V3.0 as the current theme.

The page in question is only a test page at the moment, but I would really like to remove these thumbnails, but so far, I have had no luck.

Thanks for any input you can give.
