How to Create Tab Headers with CSS and JavaScript


Tab headers are a great way to organize and present content on a webpage. They allow users to switch between different sections of information without leaving the page. In this article, we will explore how to create tab headers using CSS and JavaScript. We will cover the necessary HTML structure, styling the tabs with CSS, and adding interactive functionality with JavaScript.

1. Overview of Tab Headers

Tab headers are a common UI element used to organize content into multiple sections, where each section represents a different category or topic. Users can click on the tabs to switch between the sections and view the corresponding content. Tab headers provide a clean and intuitive way to present information, especially when dealing with a large amount of content.

2. Setting up the HTML Structure

To create tab headers, we need to set up the HTML structure first. We will use a combination of HTML and CSS classes to define the tabs and their associated content. Here’s an example of the HTML structure:

<div class="tab-container">
  <button class="tab-button">Tab 1</button>
  <button class="tab-button">Tab 2</button>
  <button class="tab-button">Tab 3</button>
  <!-- Add more buttons for additional tabs -->

<div class="tab-content">
  <!-- Content for Tab 1 -->
<div class="tab-content">
  <!-- Content for Tab 2 -->
<div class="tab-content">
  <!-- Content for Tab 3 -->
<!-- Add more content sections for additional tabs -->

3. Styling the Tab Headers with CSS

Creating the Tab Container

First, we need to create a container for the tab headers. This container will hold all the tab buttons. We can style it using CSS to achieve the desired appearance. Here’s an example of CSS code to create a basic tab container:

.tab-container {
  display: flex;

.tab-button {
  /* Add your desired styles here */

Styling the Tab Buttons

Next, we can style the tab buttons to make them visually appealing and distinguishable. We can use CSS to set the background color, font size, padding, and other properties. Here’s an example:

.tab-button {
  background-color: #f2f2f2;
  border: none;
  color: #555;
  padding: 10px 20px;
  font-size: 16px;
  cursor: pointer;

.tab-button:hover {
  background-color: #ddd;

Styling the Active Tab

To indicate which tab is currently active, we can apply a different style to the active tab button. This helps users understand which section they are currently viewing. We can use JavaScript to toggle a CSS class on the active tab button. Here’s an example of CSS code to highlight the active tab: {
  background-color: #ddd;
  font-weight: bold;

4. Adding JavaScript Functionality

Writing the JavaScript Code

To enable tab switching functionality, we need to write JavaScript code. We will use event listeners to detect clicks on the tab buttons and update the active tab accordingly. Here’s an example of JavaScript code:

const tabButtons = document.querySelectorAll('.tab-button');
const tabContents = document.querySelectorAll('.tab-content');

tabButtons.forEach((button, index) => {
  button.addEventListener('click', () => {
    // Remove the 'active' class from all tab buttons and tab contents
    tabButtons.forEach((btn) => btn.classList.remove('active'));
    tabContents.forEach((content) => = 'none');

    // Add the 'active' class to the clicked tab button and display its corresponding content
    tabContents[index].style.display = 'block';

Implementing the Tab Switching Functionality

The JavaScript code above adds event listeners to each tab button. When a tab button is clicked, it removes the ‘active’ class from all tab buttons and tab contents. Then, it adds the ‘active’ class to the clicked tab button and displays its corresponding content.
