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";}
