Bootstrap - Environment Setup

It is very easy to setup and start using Bootstrap. This chapter will explain how to download and setup Bootstrap 5.3. We will also discuss the Bootstrap file structure, and demonstrate its usage with an example.

There are two ways to do the environment Setup in Bootstrap 5.3.

  • Compiled CSS and JS

  • Source Files

Following sections will discuss about these two steps.

Compiled CSS and JS

You can download ready to use compiled code of Bootstrap v5.3.0 here

Once downloaded, unzip the compressed folder and we see the following folder structure:

├── css/
│   ├── bootstrap-grid.css
│   ├──
│   ├── bootstrap-grid.min.css
│   ├──
│   ├── bootstrap-grid.rtl.css
│   ├──

    ├── bootstrap.bundle.min.js
    ├── bootstrap.esm.js
    ├── bootstrap.esm.min.js
    ├── bootstrap.js
    ├── bootstrap.min.js

This compressed folder contains:

  • Compiled and minified CSS bundles: Bundles of compiled and minified CSS (view a comparison of CSS files)

  • Compiled and minified JavaScript plugins: JavaScript plugins that have been minified and compiled (view a JS files comparison)

Documentation, source code, and any extra JavaScript dependencies like Popper are not included.

Source files

You can download Bootstrap source files by clicking on the download link on official site here, or you can also use the GitHub link to start downloading . You will get the Bootstrap v5.3.0 after this download.

Download Sass, JavaScript, and documentation files to customize Bootstrap using your asset pipeline. Extra tools are needed for this option.

CDN via jsDelivr

CDN (Content Delivery Network) is a free content delivery platform offered by Bootstrap. Predefined files of CSS and JS can be used without installing them in your local system using the Bootstrap CDN. You can use available Bootstrap codes by copying the link and adding them to your project.

The only condition to use the CDN is to have internet connectivity in your local system. Developers can access the complete CSS for Bootstrap CDN via jsDelivr by copying the below link:.

<link href="" rel="stylesheet" integrity="sha384-9ndCyUaIbzAi2FUVXJi0CjmCapSmO7SnpJef0486qhLnuZ2cdeRhO02iuK6FUUVM" crossorigin="anonymous">
<script src="" integrity="sha384-geWF76RCwLtnZ8qwWowPQNguL3RmwHVBC9FhGdlKrxdiJJigb/j/68SIy3Te4Bkz" crossorigin="anonymous"></script>

It is advised to add Popper before JS, preferably via CDN:

Package managers

We can also install Bootstrap into the local system using Package Manager. Let's see the commands to install Bootstrap.

Package Manager Description Commands to install
npm Install Bootstrap in your Node.js powered apps with the npm package: $ npm install bootstrap@5.3.0
yarn Install Bootstrap in your Node.js powered apps with the yarn package: $ yarn add bootstrap@5.3.0

HTML Template

A basic HTML template using Bootstrap 5.3 would look like this −

You can edit and try running this code using Edit & Run option.

<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap demo</title>
    <link href="" rel="stylesheet" integrity="sha384-9ndCyUaIbzAi2FUVXJi0CjmCapSmO7SnpJef0486qhLnuZ2cdeRhO02iuK6FUUVM" crossorigin="anonymous">
    <h1>Welcome to Tutorialspoint!</h1>
    <script src="" integrity="sha384-I7E8VVD/ismYTF4hNIPjVp/Zjvgyol6VFvRkX/vR+Vc4jQkC+hVqc2pM8ODewa9r" crossorigin="anonymous"></script>
    <script src="" integrity="sha384-geWF76RCwLtnZ8qwWowPQNguL3RmwHVBC9FhGdlKrxdiJJigb/j/68SIy3Te4Bkz" crossorigin="anonymous"></script>

Here you can see the popper.min.js, bootstrap.bundle.min.js and bootstrap.min.css files that are included to make a normal HTM file to the Bootstrapped Template.
