Hi @gmzbri,

Yes, this should work: Open the Customizer, go to Additional CSS and add:

.lg-type-postThumbnail:hover .lg-caption {
opacity: 1;
}
.lg-type-postThumbnail .lg-caption {
-webkit-transition: all 400ms ease-out;
-moz-transition: all 400ms ease-out;
transition: all 400ms ease-out;
}
.lg-caption {
opacity: 0;
}

Thank you!

Thank you!
