2. Pre-Designed Components
   Includes buttons, cards, modals, carousels, and more, saving time on designing from scratch.
3. Customizable
   Modify Bootstrap styles with Sass variables or use custom CSS to suit your project's needs.
4. Browser Compatibility
   Ensures your website works seamlessly across all modern browsers.
5. Extensive Documentation
   Offers detailed guides and examples for easy implementation.

Why Use Bootstrap?

• Saves Time: Pre-built components and utilities reduce development time.

How to Get Started with Bootstrap

1. Include Bootstrap in Your Project

You can add Bootstrap to your project via a CDN or download the files.

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/js/bootstrap.bundle.min.js"></script>

Download the Bootstrap package from getbootstrap.com and include the CSS and JavaScript files in your project.

Bootstrap Grid System

The grid system is a cornerstone of Bootstrap, enabling responsive layouts.

<div class="container">
  <div class="row">
    <div class="col-md-6">Column 1</div>
    <div class="col-md-6">Column 2</div>
  </div>
</div>

• container: Wraps the grid and ensures proper alignment.
• row: Defines a row.
• col-md-6: Specifies that the column takes up 6 of the 12 grid spaces on medium screens.

Popular Bootstrap Components

1. Buttons

Easily create styled buttons with classes.

<button class="btn btn-primary">Primary Button</button>

2. Navigation Bar

Build responsive navigation menus.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Brand</a>
</nav>

3. Cards

Display content in card layouts.

<div class="card" style="width: 18rem;">
  <div class="card-body">
    <h5 class="card-title">Card Title</h5>
    <p class="card-text">Some example text.</p>
  </div>
</div>

4. Forms

Create well-structured forms.

<form>
  <div class="mb-3">
    <label for="exampleInputEmail" class="form-label">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail">
  </div>
</form>

Bootstrap can be customized using:

1. CSS Overrides: Add custom styles in a separate CSS file.
