<div id="imgModal" class="modal-image-container">
  <span id="closeModal" class="close-modal">&times;</span>
  <img id="modalImg" src="" alt="" class="modal-image">
</div>

2) for every image, if it was clicked it will show the modal

document.querySelectorAll('.image-grid img').forEach(img => {
  img.addEventListener('click', function () {
    document.getElementById('modalImg').src = this.src;
    document.getElementById('modalImg').alt = this.alt;
    document.getElementById('imgModal').style.display = 'flex';
  });
