Image Modal (Advanced)
This is an example to demonstrate how CSS and JavaScript can work together.First, use CSS to create a modal window (dialog box), and hide it by default.
Then, use a JavaScript to show the modal window and to display the image inside the modal, when a user clicks on the image:

Example
// Get the modalvar modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a captionvar 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 modalvar span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modalspan.onclick = function() {
modal.style.display = "none";
}
