Copy and paste below code in your HTML editor between <style></style> tag.

}

*, *:before, *:after {
  box-sizing: inherit;
}

body {
  margin: 0;
}

.preview {
  width: 100%;
}

.row {
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  margin: 2rem auto;
  width: 80vw;
}

.row > .col {
  padding: 0 10px;
}

.col {
  float: left; 
  width: 33.3%;
}
   
.modal {
  display: none;
  position: fixed;
  z-index: 1;
  padding: 10px 62px 0px 62px;

  display: flex;
  flex-direction: column;
  justify-content: center;
  margin: auto;
  padding: 0 0 0 0;
  width: 80vw;

  justify-content: space-between;
}


img.preview, img.modal-preview {
  cursor: pointer;
  opacity: 0.7;
}

img.active,
.preview:hover,
.modal-preview:hover {
  opacity: 1;
}

img.hover-shadow {
  transition: 0.3s;
}

.hover-shadow:hover {
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
} 

.close {

  position: absolute;
  top: 10px;
  right: 25px;
  font-size: 35px;
  font-weight: bold;
}

.close:hover,

}

.previous:hover,
.next:hover {
  background-color: rgba(0, 0, 0, 0.8);
}
    </style>

Step 2 – Add JavaScript

We use some external JavaScript link to this code. No need to worry about this, copy and paste below code between <head></head> tag.

<script>
let slideIndex = 1;
    showSlide(slideIndex);
    
    function openLightbox() {
      document.getElementById('Lightbox').style.display = 'block';
    };
    
    function closeLightbox() {
      document.getElementById('Lightbox').style.display = 'none';
    };
    
    function changeSlide(n) {
      showSlide(slideIndex += n);
    };
    
    function toSlide(n) {
      showSlide(slideIndex = n);
    };
    
    function showSlide(n) {
      const slides = document.getElementsByClassName('slide');
      let modalPreviews = document.getElementsByClassName('modal-preview');
    
      if (n > slides.length) {
        slideIndex = 1;	
      };
      
      if (n < 1) {
        slideIndex = slides.length;
      };
    
      for (let i = 0; i < slides.length; i++) {
        slides[i].style.display = "none";
      };
      
      for (let i = 0; i < modalPreviews.length; i++) {
        modalPreviews[i].className = modalPreviews[i].className.replace(' active', '');
      };
      
      slides[slideIndex - 1].style.display = 'block';
      modalPreviews[slideIndex - 1].className += ' active';
    };
</script>
