Hey y'all, 

I am trying to add a caption overlay to my gallery on the photo galleries page while keeping the masonry grid sizing the same. I found some code on here that I plugged into the CSS and tweaked with a little bit to get the caption overlay option, here is the following code: 

/*GALLERY OVERLAY*/
.gallery-caption.gallery-caption-grid-masonry p {
  opacity: 0 !important;
}
/* ------- GALLERY CAPTIONS --------*/
.gallery-caption-grid-masonry p.gallery-caption-content {
  font-family: "Night";
  font-size: 2vw !important;
  font-weight: 500 !important;
  text-transform: uppercase;
  line-height: 1.2em;
  color: #000000;
}
figure.gallery-masonry-item {
    position: relative;
}
.gallery-caption {
    position: static;
}
/* title */
.gallery-caption-content {
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    background-color: #e0e0e0;
    display: flex;
    justify-content: center;
    align-items: center;
    z-index: 999;
    padding: 7%;
    transition: opacity ease 1000ms !important;
    opacity: 0 !important;
pointer-events: none;
}
.gallery-masonry-item:hover .gallery-caption-content {
    opacity: 75% !important;
}
/* overlay */
.gallery-masonry-item-wrapper a:after {
    background: none; /* overlay color */
    content: "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    transition: opacity ease 100ms !important;
}
.gallery-masonry-item:hover .gallery-grid-item-wrapper a:after {
    opacity: 0.50;
}
/* remove gap */
figcaption {
    padding: 0 !important;
}



figure.gallery-grid-item {
    position: relative;
}
.gallery-caption {
    position: static;
}
/* title */
.gallery-caption-content {
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    background-color: none;
    display: flex;
    justify-content: center;
    align-items: center;
    z-index: 999;
    padding: 7%;
    transition: opacity ease 1000ms !important;
    opacity: 0 !important;
pointer-events: none;
}
.gallery-grid-item:hover .gallery-caption-content {
    opacity: 25% !important;
}
/* overlay */
.gallery-grid-item-wrapper a:after {
    background: #e0e0e0; /* overlay color */
    content: "";
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    opacity: 0;
    transition: opacity ease 100ms !important;
}
.gallery-grid-item:hover .gallery-grid-item-wrapper a:after {
    opacity: 0.40;
}
/* remove gap */
figcaption {
    padding: 0 !important;
}

@media only screen and (max-width: 1400px) {
    .gallery-masonry .gallery-masonry-wrapper {
        columns: 2;
        column-gap: 0;
        height: auto!important;
        display: block!important;
        padding: 0px;
    }
    .gallery-masonry-item-wrapper {
        height: auto!important;
    }
    .gallery-masonry-item {
        position: relative!important;
        transform: none!important;
        width: 100%!important;
        display: block;
        padding: 14px!important;
        box-sizing: content-box;
    }

    .gallery-masonry .gallery-masonry-item img {
        height: 100%!important;
      	width: 100%!important;
    }
}



@media only screen and (max-width: 750px) {
    .gallery-masonry .gallery-masonry-wrapper {
        columns: 1;
        column-gap: 0;
        height: auto!important;
        display: block!important;
        padding: 0px;
    }
    .gallery-masonry-item-wrapper {
        height: auto!important;
    }
    .gallery-masonry-item {
        position: relative!important;
        transform: none!important;
        width: 100%!important;
        display: block;
        padding: 3px!important;
        box-sizing: content-box;
    }

    .gallery-masonry .gallery-masonry-item img {
        height: 100%!important;
      	width: 100%!important;
    }
}

@media only screen and (max-width: 750px) { h1 {font-size:28px!important;}}
/*END OF GALLERY OVERLAY*/

While this code has helped me create an overlay option, it messed with the borders and resized the gallery images. I am trying to figure out how to get it to keep the masonry outlay which looks like this: 

Thanks!
