How to Add a Shared Progress Bar to Your Content Pages
Adding a progress bar to your content pages can enhance user experience by providing a visual indication of how far they've progressed through the article. This can be particularly useful for long-form content, giving readers a sense of accomplishment and encouraging them to continue reading.
Imagine you're building a website with lengthy blog posts. Wouldn't it be helpful if readers could see how much of the article they've already consumed? This is where a shared progress bar comes in.
Here's a simplified example using basic HTML and CSS:
<!DOCTYPE html>
<html>
<head>
<title>Shared Progress Bar</title>
<style>
.progress-bar {
width: 100%;
height: 5px;
background-color: #ddd;
position: fixed;
bottom: 0;
left: 0;
z-index: 100;
}
.progress-bar-fill {
height: 100%;
background-color: #4CAF50;
width: 0%;
transition: width 0.5s ease;
}
</style>
</head>
<body>
<div class="progress-bar">
<div class="progress-bar-fill"></div>
</div>
<h1>Your Long-Form Content Here</h1>
<script>
// Get the progress bar elements
const progressBar = document.querySelector('.progress-bar-fill');
// Calculate the scroll position
window.addEventListener('scroll', () => {
const scrollTop = window.pageYOffset;
const scrollHeight = document.body.scrollHeight;
const clientHeight = window.innerHeight;
// Calculate percentage scrolled
const percentage = (scrollTop / (scrollHeight - clientHeight)) * 100;
// Update the progress bar width
progressBar.style.width = percentage + '%';
});
</script>
</body>
</html>
