The "w3-modal" Class
A modal can be any HTML container (like a <div>) with class="w3-modal".
The "w3-modal-content" Class
All modal content should be placed in an HTML container with class="w3-modal-content".
Modal content can be any HTML element (headings, paragraphs, images, etc.)
Open a Modal
Use any HTML element to open the modal. This is often a button or a link.
Add the onclick attribute and point to the id of the modal (id01 in our example), using the document.getElementById() method and specify a unique ID that matches the "trigger" button (id01).
Closing a Modal
To close a modal, add the w3-closebtn class to an element together with an onclick attribute that points to the id of the modal (id01). You can also close it by clicking outside of the modal (see example below).
× (×) is an HTML entity that is the preferred icon for close buttons, rather than the letter "x".
Modal Header & Footer
Inside the <div> with class="w3-modal-content", use w3-container classes to create different sections in the modal:
Example
<div id="id01" class="w3-modal">
<div class="w3-modal-content">
<header class="w3-container w3-teal">
<span onclick="document.getElementById('id01').style.display='none'"
class="w3-closebtn">×</span>
<h2>Modal Header</h2>
</header>
<div
class="w3-container">
<p>Some text..</p>
<p>Some text..</p>
</div>
<footer class="w3-container
w3-teal">
<p>Modal Footer</p>
</footer>
</div>
</div>

Animated Modals

<div class="w3-modal-content w3-animate-zoom">
<div class="w3-modal-content w3-animate-top">
<div class="w3-modal-content w3-animate-bottom">
<div class="w3-modal-content w3-animate-left">
<div class="w3-modal-content w3-animate-right">
<div class="w3-modal-content w3-animate-opacity">

You can also fade in the modal's background color (w3-modal):
Modal Image

class="w3-hover-opacity">
<div id="modal01" class="w3-modal w3-animate-zoom" onclick="this.style.display='none'">

Close the Modal
In the examples above, we use a button to close the modal. However, with a little bit of JavaScript, you can also close the modal when clicking outside of the modal box:
Example
// Get the modal
var modal = document.getElementById('id01');
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target
== modal) {
modal.style.display = "none";
}
}
