6 JavaScript Scroll Indicators
Enhance page navigation with JavaScript scroll indicators that visually track user progress through content. From slim top bars to section highlights, these interactive elements improve usability and encourage engagement on scroll-heavy sites.
Examples
Gradient Vertical Scroll Progress Bar
This is a Gradient Vertical Scroll Progress Bar. It maps the user’s vertical position to a visual meter along the right edge of the viewport. Its function is to provide an unobtrusive sense of reading progress without cluttering the main content area.
