Navigation bars are essential for websites to help users find information quickly and easily. A well-structured navigation improves user experience and keeps visitors engaged.

💼 Career

Web developers often build navigation menus using frameworks like Bootstrap to create responsive and accessible websites that work well on all devices.

1

Create the basic HTML structure with Bootstrap CSS link

Write the basic HTML5 skeleton including lang="en", meta charset="UTF-8", and meta viewport tags. Add the Bootstrap 5 CSS CDN link inside the <head>. Create an empty <nav> element inside the <body> where the navigation bar will go.

Hint

Remember to include the Bootstrap CSS link inside the <head> section for styling.

2

Add a Bootstrap container and navbar brand

Inside the existing <nav> element, add a <div> with class container-fluid. Inside this container, add a <a> element with classes navbar-brand and href set to #. The text inside this link should be Bakery.

Hint

The navbar-brand class styles the main brand or logo link in the navigation bar.

3

Add the navigation links with a collapsible menu

Inside the container-fluid div, add a button with classes navbar-toggler and type="button". Set data-bs-toggle="collapse" and data-bs-target="#navbarNav". Add aria-controls="navbarNav", aria-expanded="false", and aria-label="Toggle navigation". Inside the button, add a span with class navbar-toggler-icon. Below the button, add a div with classes collapse navbar-collapse and id navbarNav. Inside this div, add an unordered list <ul> with class navbar-nav. Inside the list, add four list items <li> each with class nav-item. Each list item contains a link <a> with class nav-link and href set to #. The link texts are Home, Menu, About Us, and Contact respectively.

Hint

The toggler button allows the menu to collapse on small screens. The collapse navbar-collapse div holds the links that show or hide.

4

Add Bootstrap JavaScript bundle for interactive toggling

Before the closing </body> tag, add a <script> tag that loads the Bootstrap 5 JavaScript bundle from the CDN: https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/js/bootstrap.bundle.min.js. This script enables the toggle button to work on small screens.
