Hide Thumbnails/Grid below each Gallery

Site URL: https://www.frangipanibeatt.com/

Hi!
I've been trying to remove/hide the thumbnails that appear if you scroll to the end of each gallery. I've tried the code below, but that unfortunately removes the thumbails from my homepage/index.

Thanks in advance!

div#container-content>#grid {
    display: none;
}

Add to Home > Design > Custom CSS

.collection-type-index.index-detail div#grid {
    display: none;
}

Thank you so so much, it worked :-)
