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>
