Code to display captions on hover for Gallery Grid: Masonry pages/blocks.

I’d like image captions to show up on hover over thumbnails in gallery masonry grid pages/blocks, as they do in Portfolio pages. I need the images to still be clickable/linkable to other pages, though. Does anyone have CSS that would accomplish this?

Thank you!

You can use this code to Custom CSS box. If it doesn't work, you can share link to page where you added gallery, we can check easier.

figure[class*="gallery"]:not(.gallery-slideshow-item) {
    position: relative;
}
.gallery-caption {
    position: static;
}
/* title */
.gallery-caption p.gallery-caption-content {
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    display: flex;
    justify-content: center;
    align-items: center;
    z-index: 999;
    padding: 7%;
    transition: opacity ease 200ms !important;
    opacity: 0 !important;
pointer-events: none;
}
figure[class*="gallery"]:hover .gallery-caption-wrapper p.gallery-caption-content {
    opacity: 1 !important;
}
/* overlay */
div[class*="-item-wrapper"]:after {
    background: #f4f6ea; /* overlay color */
    content: "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    transition: opacity ease 200ms !important;
}
figure[class*="gallery"]:hover div[class*="-item-wrapper"]:after {
    opacity: 0.75;
}
/* remove gap */
figcaption {
    padding: 0 !important;
}
