W3.CSS Model

Last Updated : 02 Mar, 2021

In simple words, the Modal component is a dialogue box/popup window that displayed on top of the current page, once the trigger button is clicked. It must be kept in mind that W3.CSS doesn’t support nested modals as they create a bad UI experience for the user. Therefore, only one modal window is supported at a time. W3.CSS has two model classes to create and add content in the model window. And it must be noted that we have to add a close button as the model in W3.CSS doesn’t come with one.

Sr. No.	Model Class	Description
1.	w3-modal	It defines the model container.
2.	w3-modal-content	It defines the content of the model.

Follow the example below to learn how to create a model using W3.CSS:

Example:

HTML

<!DOCTYPE html> 
<html> 
  
<head> 
    <!-- Title of the page -->
    <title>GeeksForGeeks</title> 
  
    <!-- Adding W3.CSS file through external link -->
    <link rel="stylesheet" href= 
        "https://www.w3schools.com/w3css/4/w3.css">

<body> 
    <!-- w3-container is used to add 16px 
         padding to any HTML element.  -->
    <!-- w3-center is used to set the content 
         of the element to the center. -->
    <div class="w3-container w3-center"> 
  
        <!-- w3-text-green sets the text  
            colour to green. -->
        <!-- w3-xxlarge sets font size to 32px. -->
