W3.CSS Modal Classes
W3.CSS provides the following classes for modal windows:
| Class | Defines |
|---|---|
| w3-modal | The modal container |
| w3-modal-content | The modal content |
Create A Modal
The w3-modal class defines a container for a modal.
The w3-modal-content class defines the modal content.
Modal content can be any HTML element (divs, headings, paragraphs, images, etc.).
Example
<!-- Trigger/Open the Modal -->
<button onclick="document.getElementById('id01').style.display='block'"
class="w3-button">Open Modal</button>
<!-- The Modal -->
<div
id="id01" class="w3-modal">
<div class="w3-modal-content">
<div
class="w3-container">
<span onclick="document.getElementById('id01').style.display='none'"
class="w3-button w3-display-topright">×</span>
<p>Some text in the Modal..</p>
<p>Some text in the Modal..</p>

Open a Modal
Use any HTML element to open the modal. However, 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.
Close a Modal
To close a modal, add the w3-button 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).
Tip: × is the preferred HTML entity for close
icons, rather than the letter "x".
Modal Header and Footer
Use w3-container classes to create different sections inside the modal
content:
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-button w3-display-topright">×</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>

Modal As a Card
To display the modal as a card, add one of the w3-card-* classes to the
w3-modal-content container:
Example
<div class="w3-modal-content w3-card-4">

Animated Modals
Use any of the w3-animate-zoom|top|bottom|right|left classes to slide in the modal from a specific direction:
Example
<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 by setting the
w3-animate-opacity class on the w3-modal element:
Example
<div class="w3-modal w3-animate-opacity">

Modal With Tabbed Content
This example creates a modal with tabbed content:
document.getElementsByClassName("tablinkmod")[0].click();
function openCity(evt, cityName) {
var i, x, tablinks;
x = document.getElementsByClassName("city");
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinkmod");
for (i = 0; i < x.length; i++) {
tablinks[i].classList.remove("w3-light-grey");
}
document.getElementById(cityName).style.display = "block";
evt.currentTarget.classList.add("w3-light-grey");
}

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";
}
}

Advanced: Lightbox (Modal Image Gallery)
This example shows how to add an image slideshow inside a modal, to create a "lightbox":
×
❮
❯
function openModal() {
document.getElementById('myModal').style.display = "block";
}
function closeModal() {
document.getElementById('myModal').style.display = "none";
}
var slideIndex = 1;
showDivs(slideIndex);
function plusDivs(n) {
showDivs(slideIndex += n);
}
function currentDiv(n) {
showDivs(slideIndex = n);
}
function showDivs(n) {
var i;
var x = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("demo");
var captionText = document.getElementById("caption");
if (n > x.length) {slideIndex = 1}
if (n < 1) {slideIndex = x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" w3-opacity-off", "");
}
x[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " w3-opacity-off";
captionText.innerHTML = dots[slideIndex-1].alt;
}
