Make a link clickable in a container that is positioned absolute-CodePudding

I'm making a gallery and I'm using magnific popup to create it, however I have a hover event on the images that show an icon to suggest it can be viewed so I had to make it an absolute position. However, it stops the image from being clickable hence I can't open the the gallery carousel. I tried using a z-index: 1 to fix this but it didn't work. Here is my code:

$(document).ready(function() {
  $('.seller-gallery').magnificPopup({
    delegate: 'a',
    type: 'image',
    tLoading: 'Loading image #%curr%...',
    mainClass: 'mfp-img-mobile',
    gallery: {
      enabled: true,
      navigateByImgClick: true,
      preload: [0, 1] // Will preload 0 - before current, and 1 after the current image
    },
    image: {
      tError: '<a href="%url%">The image #%curr%</a> could not be loaded.',
      titleSrc: function(item) {
        return item.el.attr('title')   '<small>by Marsel Van Oosten</small>';
      }
    }
  });
});

.grid-gallery {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 1rem;
}

.gallery-item {
  cursor: pointer;
  position: relative;
  z-index: 1;
}

.gallery-item a {
  pointer-events: all;
}

.gallery-item:hover .gallery-item-info,
.gallery-item:focus .gallery-item-info {
  display: flex;
  justify-content: center;
  align-items: center;
  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.2);
}

.gallery-item-info {
  display: none;
}

.gallery-item-info span {
  display: inline-block;
}

.img-fluid {
  max-width: 100%;
  height: auto;
}

To fix your issue add pointer-events: none to the .gallery-item-info element you display over the top of the content. This will mean that it accepts no mouse input, so the event will pass through to the underlying content.

$(document).ready(function() {
  $('.seller-gallery').magnificPopup({
    delegate: 'a',
    type: 'image',
    tLoading: 'Loading image #%curr%...',
    mainClass: 'mfp-img-mobile',
    gallery: {
      enabled: true,
      navigateByImgClick: true,
      preload: [0, 1] // Will preload 0 - before current, and 1 after the current image
    },
    image: {
      tError: '<a href="%url%">The image #%curr%</a> could not be loaded.',
      titleSrc: function(item) {
        return item.el.attr('title')   '<small>by Marsel Van Oosten</small>';
      }
    }
  });
});

.grid-gallery {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 1rem;
}

.gallery-item {
  cursor: pointer;
  position: relative;
}

.gallery-item a {
  pointer-events: all;
}

.gallery-item:hover .gallery-item-info,
.gallery-item:focus .gallery-item-info {
  display: flex;

  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.2);
  pointer-events: none;

Alternative Method Using Pseudo-elements with Font Awesome

As an alternative, you could instead create the icon and gray overlay using a pseudo-element of .gallery-item a. The pseudo-element is a child of the link, so will not interfere with clicking it and it eliminates the need for an extra span element, which is removed in my example. It also makes it simple to apply the overlay to multiple linked images on a page if desired.

The use of pseudo-elements with Font Awesome is documented here: https://fontawesome.com/v5/docs/web/advanced/css-pseudo-elements

For an explanation I have commented the CSS in this example:

$(document).ready(function() {
  $('.seller-gallery').magnificPopup({
    delegate: 'a',
    type: 'image',
    tLoading: 'Loading image #%curr%...',
    mainClass: 'mfp-img-mobile',
    gallery: {
      enabled: true,
      navigateByImgClick: true,
      preload: [0, 1] // Will preload 0 - before current, and 1 after the current image
    },
    image: {
      tError: '<a href="%url%">The image #%curr%</a> could not be loaded.',
      titleSrc: function(item) {
        return item.el.attr('title')   '<small>by Marsel Van Oosten</small>';
      }
    }
  });
});

/*
For this example I've made the images display: block so there is no baseline whitespace and I've fixed the image width at 500px;
*/
.gallery-item {
  width: 500px;
}
.gallery-item img {
  display: block;
  width: 100%;
}

.gallery-item a {
  /*Make the icon and overlay position relative to each a link*/
  position: relative;
}

.gallery-item a::before {
  /* The icon text as per https://fontawesome.com/v5/docs/web/advanced/css-pseudo-elements */
  font-style: normal;
  font-variant: normal;
  text-rendering: auto;
  -webkit-font-smoothing: antialiased;
  font-family: "Font Awesome 5 Free";
  font-weight: 900;
  /*The icon unicode value as per https://fontawesome.com/icons/eye?s=solid*/
  content: "\f06e";
  /*Give the icon size*/
  font-size: 2em;
  /*Give the icon color*/
  color: #FFF;
  /*Center the icon and gray overlay*/
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  display: flex;
  justify-content: center;
  align-items: center;
  background: rgba(0, 0, 0, 0.2);
  /*A smooth transition from 0 opacity to 1 opacity on hover*/
  transition: opacity 0.3s linear;
  /*Invisible when not hovered*/
  opacity: 0;
}

.gallery-item a:hover::before {
  /*Visible when hovered*/
  opacity: 1;
}
