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>
</div>
</div>
</div>

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 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>
</div>

<div class="w3-modal-content w3-animate-bottom">
<div class="w3-modal-content w3-animate-left">

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 the modal box:
Example
// Get the modal
var modal = document.getElementById('id01');
// When the user clicks anywhere outside the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
