How to Create Tabs and Accordions Using JavaScript.

By Kene Samuel #programming

Creating tabs and accordions with JavaScript can significantly enhance the usability and organization of your web content. This tutorial on JavaScript tabs and accordions will allow users to navigate and interact with different sections of your website efficiently. In this article, we’ll guide you through the process of creating both tabs and accordions using HTML, CSS, and JavaScript.

Introduction to Tabs and Accordions

Tabs and accordions are popular UI components used to organize content on a web page. Tabs allow users to switch between different sections of content without leaving the page, while accordions expand and collapse sections to reveal or hide content.

Creating Tabs

HTML Structure

First, let’s create the HTML structure for the tabs. We’ll have a container for the tab buttons and another for the tab content.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Tabs and Accordions</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="tab-container">
        <div class="tab-buttons">
            <button class="tab-button active" data-tab="tab1">Tab 1</button>
            <button class="tab-button" data-tab="tab2">Tab 2</button>
            <button class="tab-button" data-tab="tab3">Tab 3</button>
        </div>
        <div class="tab-content active" id="tab1">Content for Tab 1</div>
        <div class="tab-content" id="tab2">Content for Tab 2</div>
        <div class="tab-content" id="tab3">Content for Tab 3</div>
    </div>

    <script src="scripts.js"></script>
</body>
</html>

CSS Styling

Next, let’s style the tabs to make them visually appealing.

* {
    box-sizing: border-box;
}

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 20px;
}

.tab-container {
    width: 100%;
    max-width: 600px;
    margin: auto;
}

.tab-buttons {
    display: flex;
    justify-content: space-around;
    margin-bottom: 20px;
}

.tab-button {
    padding: 10px 20px;
    cursor: pointer;
    background-color: #f1f1f1;
    border: none;
    border-radius: 5px;
    outline: none;
}

.tab-button.active {
    background-color: #007bff;
    color: white;
}

.tab-content {
    display: none;
    padding: 20px;
    border: 1px solid #ddd;
    border-radius: 5px;
    background-color: #f9f9f9;
}

.tab-content.active {
    display: block;
}

JavaScript Functionality

Now, let’s add JavaScript to handle the tab switching functionality.

document.addEventListener('DOMContentLoaded', () => {
    const tabButtons = document.querySelectorAll('.tab-button');
    const tabContents = document.querySelectorAll('.tab-content');

    tabButtons.forEach(button => {
        button.addEventListener('click', () => {
            tabButtons.forEach(btn => btn.classList.remove('active'));
            tabContents.forEach(content => content.classList.remove('active'));

            button.classList.add('active');
            document.getElementById(button.getAttribute('data-tab')).classList.add('active');
        });
    });
});

Creating Accordions

HTML Structure

Let’s create the HTML structure for the accordion.

<div class="accordion-container">
    <div class="accordion-item">
        <button class="accordion-button">Accordion 1</button>
        <div class="accordion-content">
            <p>Content for Accordion 1</p>
        </div>
    </div>
    <div class="accordion-item">
        <button class="accordion-button">Accordion 2</button>
        <div class="accordion-content">
            <p>Content for Accordion 2</p>
        </div>
    </div>
    <div class="accordion-item">
        <button class="accordion-button">Accordion 3</button>
        <div class="accordion-content">
            <p>Content for Accordion 3</p>
        </div>
    </div>
</div>

CSS Styling

Next, let’s style the accordion.

.accordion-container {
    width: 100%;
    max-width: 600px;
    margin: auto;
}

.accordion-item {
    margin-bottom: 10px;
}

.accordion-button {
    width: 100%;
    padding: 10px;
    cursor: pointer;
    background-color: #f1f1f1;
    border: none;
    border-radius: 5px;
    outline: none;
    text-align: left;
}

.accordion-content {
    display: none;
    padding: 10px;
    border: 1px solid #ddd;
    border-radius: 5px;
    background-color: #f9f9f9;
}

JavaScript Functionality

Let’s add JavaScript to handle the accordion functionality.

document.addEventListener('DOMContentLoaded', () => {
    const accordionButtons = document.querySelectorAll('.accordion-button');

    accordionButtons.forEach(button => {
        button.addEventListener('click', () => {
            const content = button.nextElementSibling;
            if (content.style.display === 'block') {
                content.style.display = 'none';
            } else {
                document.querySelectorAll('.accordion-content').forEach(content => content.style.display = 'none');
                content.style.display = 'block';
            }
        });
    });
});

Now, let’s integrate both the tab and accordion HTML structure together. Here’s the updated HTML file that includes both the tabs and the accordion:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Tabs and Accordions</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="tab-container">
        <div class="tab-buttons">
            <button class="tab-button active" data-tab="tab1">Tab 1</button>
            <button class="tab-button" data-tab="tab2">Tab 2</button>
            <button class="tab-button" data-tab="tab3">Tab 3</button>
        </div>
        <div class="tab-content active" id="tab1">Content for Tab 1</div>
        <div class="tab-content" id="tab2">Content for Tab 2</div>
        <div class="tab-content" id="tab3">Content for Tab 3</div>
    </div>

    <div class="accordion-container">
        <div class="accordion-item">
            <button class="accordion-button">Accordion 1</button>
            <div class="accordion-content">
                <p>Content for Accordion 1</p>
            </div>
        </div>
        <div class="accordion-item">
            <button class="accordion-button">Accordion 2</button>
            <div class="accordion-content">
                <p>Content for Accordion 2</p>
            </div>
        </div>
        <div class="accordion-item">
            <button class="accordion-button">Accordion 3</button>
            <div class="accordion-content">
                <p>Content for Accordion 3</p>
            </div>
        </div>
    </div>

    <script src="scripts.js"></script>
</body>
</html>

And here is the combined CSS:

* {
    box-sizing: border-box;
}

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 20px;
}

.tab-container {
    width: 100%;
    max-width: 600px;
    margin: auto;
}

.tab-buttons {
    display: flex;
    justify-content: space-around;
    margin-bottom: 20px;
}

.tab-button {
    padding: 10px 20px;
    cursor: pointer;
    background-color: #f1f1f1;
    border: none;
    border-radius: 5px;
    outline: none;
}

.tab-button.active {
    background-color: #007bff;
    color: white;
}

.tab-content {
    display: none;
    padding: 20px;
    border: 1px solid #ddd;
    border-radius: 5px;
    background-color: #f9f9f9;
}

.tab-content.active {
    display: block;
}

.accordion-container {
    width: 100%;
    max-width: 600px;
    margin: auto;
}

.accordion-item {
    margin-bottom: 10px;
}

.accordion-button {
    width: 100%;
    padding: 10px;
    cursor: pointer;
    background-color: #f1f1f1;
    border: none;
    border-radius: 5px;
    outline: none;
    text-align: left;
}

.accordion-content {
    display: none;
    padding: 10px;
    border: 1px solid #ddd;
    border-radius: 5px;
    background-color: #f9f9f9;
}

And here is the combined JavaScript:

document.addEventListener('DOMContentLoaded', () => {
    // Tab functionality
    const tabButtons = document.querySelectorAll('.tab-button');
    const tabContents = document.querySelectorAll('.tab-content');

    tabButtons.forEach(button => {
        button.addEventListener('click', () => {
            tabButtons.forEach(btn => btn.classList.remove('active'));
            tabContents.forEach(content => content.classList.remove('active'));

            button.classList.add('active');
            document.getElementById(button.getAttribute('data-tab')).classList.add('active');
        });
    });

    // Accordion functionality
    const accordionButtons = document.querySelectorAll('.accordion-button');

    accordionButtons.forEach(button => {
        button.addEventListener('click', () => {
            const content = button.nextElementSibling;
            if (content.style.display === 'block') {
                content.style.display = 'none';
            } else {
                document.querySelectorAll('.accordion-content').forEach(content => content.style.display = 'none');
                content.style.display = 'block';
            }
        });
    });
});
document.addEventListener('DOMContentLoaded', () => {
    // Tab functionality
    const tabButtons = document.querySelectorAll('.tab-button');
    const tabContents = document.querySelectorAll('.tab-content');

    tabButtons.forEach(button => {
        button.addEventListener('click', () => {
            tabButtons.forEach(btn => btn.classList.remove('active'));
            tabContents.forEach(content => content.classList.remove('active'));

            button.classList.add('active');
            document.getElementById(button.getAttribute('data-tab')).classList.add('active');
        });
    });

    // Accordion functionality
    const accordionButtons = document.querySelectorAll('.accordion-button');

    accordionButtons.forEach(button => {
        button.addEventListener('click', () => {
            const content = button.nextElementSibling;
            if (content.style.display === 'block') {
                content.style.display = 'none';
            } else {
                document.querySelectorAll('.accordion-content').forEach(content => content.style.display = 'none');
                content.style.display = 'block';
            }
        });
    });
});

This combined setup allows you to have both tabs and accordions on the same webpage, making it a versatile and organized way to present content to users.

Here’s the result!

Conclusion
