<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.
</p> <p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.
</p>
<img id="myImg" src="img_snow.jpg" alt="Snow1" style="width:100%;max-width:300px"> <img id="myImg2" src="7.jpg" alt="Snow2" style="width:100%;max-width:300px">
<!-- The Modal -->
<div id="myModal" class="modal"> <img class="modal-content" id="img01">
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the
<span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on
<span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg2');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;

// Get the
