🚀 What Is Bootstrap?

Bootstrap is a front-end toolkit that provides:

  • A grid system for responsive layout
  • Predefined UI components like buttons, navbars, modals, and more
  • Hundreds of utility classes (margins, padding, colors, alignment, etc.)
  • JavaScript components with dynamic behaviors

📦 Ways to Use Bootstrap

There are several methods to include Bootstrap in a project. Each method depends on your setup and goals.

1. ✅ CDN (The Quickest Way)

Just paste the following into your HTML file:

href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">


<span class="na">src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js">

2. 📦 Using NPM (For Projects with Webpack, Vite, etc.)

If you're building a modern JavaScript project, install Bootstrap with:

npm install bootstrap

Then import it in your JavaScript:

// JS (includes Popper)
import 'bootstrap/dist/js/bootstrap.bundle.min.js'

// Optionally: import CSS
import 'bootstrap/dist/css/bootstrap.min.css'

You can also import SCSS for full customization:

// SCSS entry file
@import "node_modules/bootstrap/scss/bootstrap";

3. 🔄 Integration with Frameworks

Bootstrap can be used in any web framework. Here's how:

🔹 React

Use react-bootstrap or import Bootstrap styles directly.

npm install react-bootstrap bootstrap

In your app:

import 'bootstrap/dist/css/bootstrap.min.css'
import { Button } from 'react-bootstrap'

<Button variant="primary">Click me</Button>

🔹 Angular

Use ng-bootstrap or manually include the styles:

npm install bootstrap

In angular.json:

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
  "node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"
]

🔹 Laravel / Symfony

Bootstrap is often included via Laravel Mix or Webpack Encore.

Laravel Example:

npm install bootstrap

Then in your resources/js/app.js:

import 'bootstrap'

And in your resources/sass/app.scss:

@import "~bootstrap/scss/bootstrap";

Run:

npm run dev

4. 🎨 Customization with SCSS (Professional Workflow)

Bootstrap is built with Sass. You can override variables and create a custom theme:

  • Copy Bootstrap’s _variables.scss
  • Change colors, font sizes, breakpoints, etc.
  • Import in your own SCSS file before the main import: 
// Your overrides
$primary: #ff5733;
$font-family-base: 'Inter', sans-serif;

@import "bootstrap/scss/bootstrap";

This allows full control over your design system.
