Learn How to Create a Section Counter with CSS

In today’s digital world, web developers and designers are constantly looking for innovative ways to enhance user experiences. One such enhancement is the “section counter,” which provides users with a clear indication of their progress as they scroll through a webpage. In this article, we will learn how to create a section counter with CSS. We will explain the process in detail, providing code snippets to make implementation easy and efficient.

What is a Section Counter?

A section counter is a user interface element that keeps track of the sections a user has scrolled through on a webpage. It often appears as a small indicator in the corner of the screen, updating as the user navigates through different sections of a long webpage. Section counters are useful for lengthy articles, tutorials, or websites with multiple sections, as they provide users with a sense of progress and navigation.

The Importance of Section Counters

Section counters serve various purposes:

  • Enhanced User Experience: They help users navigate through long content, making it easier to find specific information.
  • Engagement: Section counters can encourage users to continue scrolling and exploring a webpage.
  • Visual Appeal: They add a visually appealing element to your website, improving its overall aesthetics.

Setting Up the HTML Structure

To create a section counter, you’ll first need to set up the HTML structure of your webpage. Below is an example of how your HTML should be organized:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Section Counter Example</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <section id="section1"> <!-- Your content here --> </section>
    <section id="section2"> <!-- Your content here --> </section>
    <section id="section3"> <!-- Your content here --> </section>
    <!-- Add more sections as needed -->
</body>
</html>

Styling with CSS

Next, let’s style our section counter. Create a CSS file (e.g., styles.css) and add the following CSS code:

/* CSS for Section Counter */
#section-counter {
    position: fixed;
    top: 20px;
    right: 20px;
    background-color: #333;
    color: #fff;
    padding: 10px 15px;
    border-radius: 5px;
    font-size: 18px;
}

Adding JavaScript for Functionality

Now, it’s time to add JavaScript to make our section counter-functional. Here’s the JavaScript code:

// JavaScript for Section Counter
window.addEventListener('scroll', () => {
    const sections = document.querySelectorAll('section');
    let currentSection = '';

    sections.forEach((section) => {
        const sectionTop = section.offsetTop;
        const sectionHeight = section.clientHeight;

        if (pageYOffset >= sectionTop - sectionHeight / 3) {
            currentSection = section.getAttribute('id');
        }
    });

    document.querySelector('#section-counter').innerHTML = `Section: ${currentSection}`;
});
