2. Step-by-Step Guide

Bootstrap is a popular framework designed to simplify the process of front-end development. It provides pre-made design templates for typography, forms, buttons, navigation, and other interface components.

The Bootstrap grid system utilizes a series of containers, rows, and columns to layout and align content. It's built with flexbox and is fully responsive.

Here's how to get started with a responsive navbar:

Setup Bootstrap

Before building the navbar, we need to include the Bootstrap CSS and JavaScript files in our HTML file.

<!DOCTYPE html>
<html>
<head>
  <title>Responsive Navbar</title>
  <!-- Bootstrap CSS -->
  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css">
</head>
<body>
  <!-- Your content goes here -->

  <!-- Bootstrap JS and jQuery -->
  <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
  <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js"></script>
</body>
</html>

3. Code Examples

Building the Navbar

Here's the basic structure of a responsive navbar in Bootstrap:

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

  <!-- Toggler/collapsible Button -->
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <!-- Navbar links -->
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricing</a>
      </li>
    </ul>
  </div>
</nav>
