Create Hoverable Sidebar Menu in HTML CSS and JavaScript
![](https://exousiaamedia.com/wp-content/uploads/2023/10/images-6.jpeg)
With the unique idea of sites on the web, the sort, UI, and client experience plan of the sidebar menu are continually advancing. One recognizable pattern is the development of sidebar menus that extend and fall upon mouse float.
Hoverable sidebar menus are a particular sort of sidebar that consumes insignificant space on a site page, at first showing up as little symbols. However, after floating over them, they grow and uncover their total substance.
In this blog entry, I will give a bit by bit guide on making a responsive hoverable sidebar menu utilizing HTML, CSS, and JavaScript. To improve the client experience, the sidebar will have a lock symbol at the top, permitting clients to empower or cripple the hoverable element on the menu without any problem.
Steps For Creating Sidebar Menu in HTML and CSS
To create a hoverable Sidebar Menu using HTML CSS and JavaScript follow the given steps line by line:
- Create a folder. You can name this folder whatever you want, and inside this folder, create the mentioned files.
- Create an
index.html
file. The file name must be index and its extension .html - Create a
style.css
file. The file name must be style and its extension .css - Create a
script.js
file. The file name must be script and its extension .js
Index.html file
To start, add the following HTML codes to your index.html
 file: These codes include all the necessary CDN links and HTML sidebar layout.

Styles.css File
Next, include the following CSS code in your style.css
 file to implement styling to the elements and employ media queries for ensuring responsiveness on various screen sizes. You can modify this code according to your preferences by adjusting properties such as color, font, size, and other CSS attributes to achieve your desired design.

Script.js File
Lastly, added the provided JavaScript code to your script.js
 file to enable the functionality of expanding and collapsing the sidebar on mouse hover.
// Selecting the sidebar and buttons
const sidebar = document.querySelector(".sidebar");
const sidebarOpenBtn = document.querySelector("#sidebar-open");
const sidebarCloseBtn = document.querySelector("#sidebar-close");
const sidebarLockBtn = document.querySelector("#lock-icon");
// Function to toggle the lock state of the sidebar
const toggleLock = () => {
sidebar.classList.toggle("locked");
// If the sidebar is not locked
if (!sidebar.classList.contains("locked")) {
sidebar.classList.add("hoverable");
sidebarLockBtn.classList.replace("bx-lock-alt", "bx-lock-open-alt");
} else {
sidebar.classList.remove("hoverable");
sidebarLockBtn.classList.replace("bx-lock-open-alt", "bx-lock-alt");
}
};
// Function to hide the sidebar when the mouse leaves
const hideSidebar = () => {
if (sidebar.classList.contains("hoverable")) {
sidebar.classList.add("close");
}
};
// Function to show the sidebar when the mouse enter
const showSidebar = () => {
if (sidebar.classList.contains("hoverable")) {
sidebar.classList.remove("close");
}
};
// Function to show and hide the sidebar
const toggleSidebar = () => {
sidebar.classList.toggle("close");
};
// If the window width is less than 800px, close the sidebar and remove hoverability and lock
if (window.innerWidth < 800) {
sidebar.classList.add("close");
sidebar.classList.remove("locked");
sidebar.classList.remove("hoverable");
}
// Adding event listeners to buttons and sidebar for the corresponding actions
sidebarLockBtn.addEventListener("click", toggleLock);
sidebar.addEventListener("mouseleave", hideSidebar);
sidebar.addEventListener("mouseenter", showSidebar);
sidebarOpenBtn.addEventListener("click", toggleSidebar);
sidebarCloseBtn.addEventListener("click", toggleSidebar);
