Understanding the Core Concepts of Bootstrap Jumbotron and Toasts
Bootstrap Jumbotron and Toasts: A Detailed Explanation
Bootstrap Jumbotron
The Jumbotron component is a container used for creating attention-grabbing introductory content or calls to action on a website. This large, full-width component comes with a padding and margin that helps in highlighting the content within it, making it stand out from other elements on the page.
Key Features of Bootstrap Jumbotron:
Simplicity and Responsiveness:
- Jumbotron adapts to different screen sizes due to Bootstrap's responsive grid system. Its dimensions automatically adjust to ensure it looks great on mobile, tablet, and desktop devices.
Customizable Styling:
- The Jumbotron comes with default styling, but it is easily customizable. You can change its background color, text color, padding, and other properties to match the design of your site.
Ideal for Calls to Action:
- Usually placed at the top of a webpage or within significant sections of a webpage, a Jumbotron is perfect for providing introductory content, storytelling, or offering a clear call to action.
How to Use Jumbotron in Bootstrap: To create a Jumbotron, include the following HTML code snippet within your project:
<div class="jumbotron jumbotron-fluid">
<div class="container">
<h1 class="display-4">Welcome to the Bootstrap Jumbotron!</h1>
<p class="lead">This is a simple paragraph displaying inside a Bootstrap Jumbotron. It includes a call-to-action button to demonstrate its capability to highlight important information.</p>
<a class="btn btn-primary btn-lg" href="#" role="button">Learn More</a>
</div>
</div>
Important Information:
- Jumbotron Fluid: Use the class
jumbotron-fluidto make the jumbotron full-width, stretching across the whole viewport. - Grid System: Since the Jumbotron utilizes Bootstrap's grid system, it provides an excellent layout option for flexible containers.
- Combining with Other Components: Jumbotrons can be combined with other Bootstrap components such as buttons, navbars, and carousels for enhanced functionality.
Bootstrap Toasts
Toasts are small, customizable alerts that pop up at the top of your webpage to provide feedback to users without obstructing the main content. Perfect for displaying notifications, alerts, or online chat messages, the Toast component enhances interactivity on your site.
Key Features of Bootstrap Toasts:
Automatic Removal:
- Toasts are designed to disappear automatically after a set period, which can be adjusted based on UX preferences.
Manual Control:
- Users can manually dismiss toasts by clicking a close button, offering them the flexibility to control the duration of notification visibility.
Customizable Timing:
- The duration for which a toast is displayed can be adjusted using data attributes such as
data-delay.
- The duration for which a toast is displayed can be adjusted using data attributes such as
How to Use Toasts in Bootstrap: To create a Toast, you need to write the following HTML code:
<div class="toast" role="alert" aria-live="assertive" aria-atomic="true" data-delay="5000">
<div class="toast-header">
<strong class="mr-auto">Bootstrap Toast Example</strong>
<small class="text-muted">Just now</small>
<button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="toast-body">
Your message or notification goes here.
</div>
</div>
Important Information:
- Data Attributes: Toasts use data attributes to manage their behavior, such as
data-delayfor timing anddata-autohidefor automatic removal. - JavaScript Integration: Bootstrap’s Toast component relies on JavaScript for functionality, so ensure that the required scripts are included in your project.
- Customization: Customize the Toast’s appearance using Bootstrap’s utility classes or write your CSS rules to achieve the desired look.

Step-by-Step Guide: How to Implement Bootstrap Jumbotron and Toasts
Bootstrap Jumbotron Example
The Jumbotron is a fluid container that can extend the entire width of a viewport to showcase key content on your site.
Step 1: Include Bootstrap in Your Project
First, you need to include Bootstrap in your HTML file. There are several ways to do this, but the easiest way is to use a CDN.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap Jumbotron Example</title>
<!-- Bootstrap CSS -->
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<!-- Your Jumbotron content goes here -->
<!-- Bootstrap JS and its dependencies -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</body>
</html>
Step 2: Create the Jumbotron
Inside the body tag, add the Jumbotron component.
<div class="jumbotron jumbotron-fluid">
<div class="container">
<h1 class="display-4">Welcome to Our Website!</h1>
<p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
<button type="button" class="btn btn-primary">Learn More</button>
</div>
</div>
Full Code Example
Here is the full HTML code combining steps 1 and 2:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap Jumbotron Example</title>
<!-- Bootstrap CSS -->
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="jumbotron jumbotron-fluid">
<div class="container">
<h1 class="display-4">Welcome to Our Website!</h1>
<p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
<button type="button" class="btn btn-primary">Learn More</button>
</div>
</div>
<!-- Bootstrap JS and its dependencies -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</body>
</html>
Visit this code in a browser, and you'll see a beautiful, responsive Jumbotron displaying a welcome message.
Bootstrap Toasts Example
Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems.
Step 1: Include Bootstrap in Your Project
As before, let’s include Bootstrap using a CDN. If you’ve already done this in your Jumbotron example, you can skip this step.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap Toasts Example</title>
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
<!-- Your Toast containers go here -->
<!-- Bootstrap JS and its dependencies -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</body>
</html>
Step 2: Create the Toast Container
Toasts require a wrapping element for positioning (using .toast-container class). You can place this container wherever you like in your HTML structure.
<div id="liveToastBtn">
<button type="button" class="btn btn-primary mt-4" id="liveToastBtn">Show live toast</button>
</div>
<div class="position-fixed bottom-0 end-0 p-3" style="z-index: 11">
<div id="liveToast" class="toast" role="alert" aria-live="assertive" aria-atomic="true">
<div class="toast-header">
<img src="..." class="rounded mr-2" alt="...">
<strong class="mr-auto">Bootstrap</strong>
<small>11 mins ago</small>
<button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="toast-body">
Hello, world! This is a toast message.
</div>
</div>
</div>
Make sure to add a button that will trigger the toast.
Step 3: Add JavaScript to Show Toast
In the previous code, we added a button to show the toast. However, Bootstrap's JavaScript needs to be initialized with additional script to show the toast when you click the button.
<script>
$(document).ready(function(){
$('#liveToastBtn').click(function(){
$('#liveToast').toast('show');
});
});
</script>
Alternatively, you can configure the toast in your HTML without writing any JavaScript using the autoload="true" and autoclose attributes.
However, these options are not directly available in Bootstrap's standard implementation without modifying the source code. For simplicity, let’s use jQuery to show the toast.
Full Code Example
Here’s the complete code combining steps 1, 2, and 3:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap Toasts Example</title>
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
<div id="liveToastBtn">
<button type="button" class="btn btn-primary mt-4" id="liveToastBtn">Show live toast</button>
</div>
<div class="position-fixed bottom-0 end-0 p-3" style="z-index: 11">
<div id="liveToast" class="toast" role="alert" aria-live="assertive" aria-atomic="true">
<div class="toast-header">
<img src="..." class="rounded mr-2" alt="...">
<strong class="mr-auto">Bootstrap</strong>
<small>11 mins ago</small>
<button type="button" class="ml-2 mb-1 close" data-dismiss="toast" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="toast-body">
Hello, world! This is a toast message.
</div>
</div>
</div>
<!-- Bootstrap JS and its dependencies -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
<script>
$(document).ready(function(){
$('#liveToastBtn').click(function(){
$('#liveToast').toast('show');
});
});
</script>
</body>
</html>
Replace <img src="..." class="rounded mr-2" alt="..."> with a path to an image if you want one to appear along your toast.
When you run this, clicking the "Show live toast" button will display a toast at the bottom-right corner of the screen that says "Hello, world! This is a toast message."

1. What is a Bootstrap Jumbotron?
Answer: A Bootstrap Jumbotron is a lightweight, flexible component used to showcase important preset content or information in Bootstrap 3. It's commonly used for marketing and can easily be customized to fit a variety of needs. However, it was removed in Bootstrap 4 and later versions due to a redesign. Instead, developers are encouraged to create similar large content areas using .jumbotron-like classes or other Bootstrap utilities.

<div class="p-5 mb-4 bg-light rounded-3">
<div class="container-fluid py-5">
<h1 class="display-5 fw-bold">Welcome to My Website</h1>
<p class="col-md-8 fs-4">Using a series of utilities, you can create this Jumbotron, just like the one in Bootstrap 3. Check out the examples below for how you can remix and restyle it to your liking.</p>
<button class="btn btn-primary btn-lg" type="button">Example button</button>
</div>
</div>

if (button2) {
button2.addEventListener('click', function () {
toast2.show()
})
}
</script>
8. What is the difference between a Bootstrap Toast and a Bootstrap Notify?
Answer: A Bootstrap Toast is a built-in Bootstrap component that provides a simple and clean way to show short pieces of information or notifications. Bootstrap Notify is a third-party library that offers more customization options for notifications beyond what Bootstrap Toast provides. It allows for more complex behaviors and styles, but requires additional setup and linking to an external script.
9. Can I use JavaScript to programmatically control the display duration of a Bootstrap Toast?
Answer: Yes, you can programmatically control the duration of a Bootstrap Toast by setting the autohide and delay options when initializing the Toast with JavaScript.
<div class="toast" role="alert" aria-live="assertive" aria-atomic="true" id="programmaticToast">
<div class="toast-header">
<strong class="me-auto">Bootstrap</strong>
<small class="text-muted">5 seconds ago</small>
<button type="button" class="btn-close" data-bs-dismiss="toast" aria-label="Close"></button>
</div>
<div class="toast-body">
This toast will auto-hide after 5 seconds.
</div>
</div>
<script>
var toastElList = [].slice.call(document.querySelectorAll('.toast'))
var toastList = toastElList.map(function(toastEl) {
return new bootstrap.Toast(toastEl, {
autohide: true,
delay: 5000 // milliseconds
});
});
</script>
10. Can I show a Bootstrap Toast multiple times without refreshing the page?
Answer: Yes, you can show a Bootstrap Toast multiple times without refreshing the page. Just ensure that the Toast element is not removed from the DOM and that the .show() method is called on the Toast instance repeatedly. Here's how:
