Let's start building our responsive navigation bar by setting up the HTML5 markup. This markup provides the foundation for structuring and organizing our navigation elements. Here's a breakdown of the key elements used:
<!DOCTYPE html>: This declaration specifies the document type and version of HTML being used.<html>: The root element that encases the entire HTML document.<head>: The section containing metadata and references to external resources.<title>: Specifies the title of the webpage, visible in the browser's title bar or tab.<link rel="stylesheet" href="styles.css">: Connects the external CSS file to apply styles.
<!DOCTYPE html>
<html>
<head>
<title>Responsive Navigation Bar</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<nav class="navbar" id="navbar">
<div class="navbar-toggle" id="navbar-toggle">
<span class="bar"></span>
<span class="bar"></span>
<span class="bar"></span>
</div>
<ul class="navbar-list" id="navbar-list">
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Services</a></li>
<li><a href="#">Portfolio</a></li>
<li><a href="#">Contact</a></li>
</ul>
</nav>
<script src="script.js"></script>
</body>
</html>
Styling for Flexibility: CSS3 Styles
To ensure our navigation bar is visually appealing and flexible across devices, we'll use CSS3 for styling. Flexbox, a layout model in CSS3, will enable us to create a responsive layout with ease. Here's an overview of the CSS styles applied:
.navbar: The container for our navigation bar, with background color, flex properties, and padding..navbar-toggle: The element responsible for toggling the mobile menu, using Flexbox for its appearance..bar: Represents the individual bars of the hamburger icon, styled with width, height, and background color..navbar-list: The list containing navigation items, displayed in a row using Flexbox..navbar-list li: Styling for list items (menu items), with margin for spacing.- Media Queries (
@media): These queries apply specific styles when the screen size falls below 768px, making the navigation bar mobile-friendly..navbar-list: Converts the navigation items into a vertical column layout..navbar-list.show: Displays the mobile menu when toggled..navbar-toggle: Displays the hamburger icon on smaller screens.
/* styles.css */
body {
margin: 0;
font-family: Arial, sans-serif;
}
.navbar {
background-color: #333;
overflow: hidden;
display: flex;
justify-content: space-between;
align-items: center;
padding: 10px;
}
.navbar-toggle {
display: none;
flex-direction: column;
cursor: pointer;
}
.bar {
width: 25px;
height: 3px;
background-color: #fff;
margin: 2px 0;
}
.navbar-list {
list-style-type: none;
display: flex;
}
.navbar-list li {
margin-right: 20px;
}
.navbar-list li a {
text-decoration: none;
color: #fff;
}
@media screen and (max-width: 768px) {
.navbar-list {
display: none;
flex-direction: column;
background-color: #333;
width: 100%;
position: absolute;
top: 60px;
left: 0;
text-align: center;
transition: all 0.3s ease-in-out;
}
.navbar-list.show {
display: flex;
}
.navbar-list li {
margin: 10px 0;
}
.navbar-toggle {
display: flex;
}
}
Creating Interactivity: JavaScript Behavior
Adding interactivity to our navigation bar is achieved through JavaScript. We create functionality that toggles the visibility of the mobile menu when the hamburger icon is clicked. Here's a breakdown of the JavaScript used:
const navbarToggle: Retrieves the element with the ID "navbar-toggle."const navbarList: Retrieves the element with the ID "navbar-list."navbarToggle.addEventListener("click", ...): Adds a click event listener to the navbar toggle element, toggling the "show" class on the navbar list when clicked.
/* script.js */
const navbarToggle = document.getElementById("navbar-toggle");
const navbarList = document.getElementById("navbar-list");
navbarToggle.addEventListener("click", () => {
navbarList.classList.toggle("show");
});
