Bootstrap 5 Get Started
What is Bootstrap?
- Bootstrap is a free front-end framework for faster and easier web development
- Bootstrap includes HTML and CSS based design templates for typography, forms, buttons, tables, navigation, modals, image carousels and many other, as well as optional JavaScript plugins
- Bootstrap also gives you the ability to easily create responsive designs
What is Responsive Web Design?
Responsive web design is about creating web sites which automatically adjust
themselves to look good on all devices, from small phones to large desktops.

Try it Yourself »Bootstrap Versions
Bootstrap 5 (released 2021) is the newest version of Bootstrap (released 2013); with new components, faster stylesheet and more responsiveness.
Bootstrap 5 supports the latest, stable releases of all major browsers and platforms. However, Internet Explorer 11 and down is not supported.
The main differences between Bootstrap 5 and Bootstrap 3 & 4, is that Bootstrap 5 has switched to vanilla JavaScript instead of jQuery.
Note: Bootstrap 3 and Bootstrap 4 is still supported by the team for critical bugfixes and documentation changes, and it is perfectly safe to continue to use them. However, new features will NOT be added to them.
Why Use Bootstrap?
Advantages of Bootstrap:
- Easy to use: Anybody with just basic knowledge of HTML and CSS can start using Bootstrap
- Responsive features: Bootstrap's responsive CSS adjusts to phones, tablets, and desktops
- Mobile-first approach: In Bootstrap, mobile-first styles are part of the core framework
- Browser compatibility: Bootstrap 5 is compatible with all modern browsers (Chrome, Firefox, Edge, Safari, and Opera). Note that if you need support for IE11 and down, you must use either BS4 or BS3.
Where to Get Bootstrap 5?
There are two ways to start using Bootstrap 5 on your own web site.
You can:
- Include Bootstrap 5 from a CDN
- Download Bootstrap 5 from getbootstrap.com
Bootstrap 5 CDN
If you don't want to download and host Bootstrap 5 yourself, you can include it from a CDN (Content Delivery Network).
jsDelivr provides CDN support for Bootstrap's CSS and JavaScript:
MaxCDN:
<!-- Latest compiled and minified CSS -->
<link
href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"
rel="stylesheet">
<!-- Latest compiled JavaScript -->
<script
src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
One advantage of using the Bootstrap 5 CDN:
Many users already have downloaded
Bootstrap 5 from jsDelivr when visiting
another site. As a result, it will be loaded from cache when they visit your site, which leads to faster loading time.
Also, most CDN's will make sure that once a user requests a file from it, it will be served
from the server closest to them, which also leads to faster loading time.
JavaScript?
Bootstrap 5 uses JavaScript for different
components (like modals, tooltips, popovers etc). However, if you just use the
CSS part of Bootstrap, you don't need them.
Downloading Bootstrap 5
If you want to download and host Bootstrap 5 yourself, go to https://getbootstrap.com/, and follow the instructions there.
Create Your First Web Page With Bootstrap 5
1. Add the HTML5 doctype
Bootstrap 5 uses HTML elements and CSS properties that require the HTML5 doctype.
Always include the HTML5 doctype at the beginning of the page, along with the lang attribute and the correct title and character set:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap 5 Example</title>
<meta charset="utf-8">
</head>
</html>
2. Bootstrap 5 is mobile-first
Bootstrap 5 is designed to be responsive to mobile devices. Mobile-first styles are part of the core framework.
To ensure proper rendering and touch zooming, add the following <meta> tag inside the
<head> element:
<meta name="viewport" content="width=device-width, initial-scale=1">
The width=device-width part sets the width of the page to follow the screen-width
of the device (which will vary depending on the device).
The initial-scale=1 part sets the initial zoom level when the page is first loaded
by the browser.
3. Containers
Bootstrap 5 also requires a containing element to wrap site contents.
There are two container classes to choose from:
- The
.containerclass provides a responsive fixed width container - The
.container-fluidclass provides a full width container, spanning the entire width of the viewport
Two Basic Bootstrap 5 Pages
The following example shows the code for a basic Bootstrap 5 page (with a responsive fixed width container):
