In this article, we will create a toggleable sidebar navigation menu using HTML, CSS, and JavaScript. The navigation menu allows users to open and close a sidebar to access various sections of a website. When the user clicks on a navigation item, the corresponding content is displayed in the main content area. We'll make the website responsive to different screen sizes for a seamless user experience.
Approach
- First, we will make nav items with the help of anchor tags.
- Now by using CSS properties like position fixed, left, and right properties, we will align the navbar to the sidebar.
- Design the navbar including headings, and paragraphs by using CSS properties.
- Change the content of the heading dynamically by using the showContent () function.
- Lastly, make a button for closing the navbar by using the function name closeNav().
Example: In this example, we write a code to build a toggleable sidebar using HTML CSS and JavaScript.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content=
"width=device-width, initial-scale=1.0" />
<link rel="stylesheet" href="style.css" />
<title>

@media screen and (min-width: 768px) {

.contentText h2 {

}
function openNav() {
document.getElementById("sideMenu")
.style.width = "300px";
document.getElementById("contentArea")
.style.marginLeft = "300px";
}
function closeNav() {
document.getElementById("sideMenu")
.style.width = "0";
document.getElementById("contentArea")
.style.marginLeft = "0";
}
function showContent(content) {
document.getElementById("contentTitle")
.textContent = content + " page";
closeNav();
}
Output:
