How to implement a scroll progress indicator in Webflow that shows page scroll completion?

Implementing a Scroll Progress Indicator in Webflow

Creating a scroll progress indicator in Webflow is a great way to enhance user experience by allowing visitors to visually track how far they have scrolled through a webpage. This guide provides a thorough, step-by-step walkthrough to add and customize a progress indicator in your Webflow project.

Prerequisites

• A Webflow account with access to a hosted project.
• Basic understanding of HTML, CSS, and JavaScript.
• Familiarity with Webflow's interface, including working with elements and applying custom code.

Step 1: Designing the Progress Indicator

• Open your Webflow project where you want the scroll progress indicator to appear.
• Navigate to the page on which you want to implement the scroll indicator.
• Add a new Div Block for the scroll progress indicator. This can be done by dragging a Div Block onto your canvas from the Add panel.
• Style the Div Block to your preference:
  • Set the Position to Fixed and align it to the top of your page.
  • Adjust the Width and Height to your liking (commonly height set to 5px for a slim progress bar).
  • Assign a background color to the Div Block that contrasts well with your page design.
  • Give the Div Block a class name, for instance, “scroll-indicator”.

Step 2: Adding Custom JavaScript

• Navigate to the Project Settings in Webflow and click on the Custom Code tab.
• Scroll down to the Footer Code section, which ensures the code runs after the page content is loaded.
• Insert the following JavaScript to update the width of the progress bar as the user scrolls:

  
    <script>
    window.onscroll = function() { scrollProgress(); };

function scrollProgress() {
  var winScroll = document.body.scrollTop || document.documentElement.scrollTop;
  var height = document.documentElement.scrollHeight - document.documentElement.clientHeight;
  var scrolled = (winScroll / height) \* 100;
  document.querySelector('.scroll-indicator').style.width = scrolled + "%";
}
&lt;/script&gt;

  
  

• Ensure you publish your site for the changes to take effect.

Step 3: Testing the Scroll Progress Indicator

• Publish your Webflow project and open the page with the implemented scroll indicator.
• Scroll down the page and observe the progress bar. It should now show the percentage of the page you have scrolled through.
• Check across different browsers and devices to ensure consistent functionality and appearance of the scroll progress indicator.

Customizing and Enhancing Your Scroll Indicator

• To change the appearance:
  • Modify the height and colors of the scroll indicator in the Webflow Designer; experiment with different styles.
  • Consider adding transitions or animations via CSS to make the scroll indicator more visually appealing.
• For added functionality:
  • Implement additional JavaScript to pause or animate the scroll indicator upon reaching 100% of the scroll, enhancing the UI experience.

By carefully following this guide, you can effectively implement and customize a scroll progress indicator in your Webflow project, providing a more interactive and informative experience for your webpage visitors.
