How can I ensure that a Lottie animation remains in place on a webpage while the content beneath it scrolls and only ends after a certain duration or number of pixels, without constantly adjusting the timing in Webflow's scroll effects?

To keep a Lottie animation fixed in place while the page scrolls and ensure it completes after a specific duration or scroll distance, follow these steps:

1. Set Up the Lottie Animation

• Add a Lottie file to your Webflow project.
• Set its positioning to fixed (so it stays in place).
• Adjust its z-index so it appears above the scrolling content.

2. Wrap It with a Scroll-Based Trigger

• Place the Lottie animation inside a div that will control its animation progress.
• Set this wrapper to relative position for proper containment.

3. Use Webflow’s Scroll Animation Feature

• Go to Interactions (lightning bolt icon) in Webflow’s sidebar.
• Create a new Page Scroll animation and select "While Page is Scrolling".
• Target the Lottie animation and set it to animate "Based on Scroll Progress".

4. Define Scroll Timing

• Adjust the Start and End percentage based on how long the animation should run.
• If you want it to last for a specific distance (e.g., 1000px), approximate the percentage based on the full page height.
• Set the Lottie animation to play from 0% to 100% within this range to achieve smooth progress.

5. Ensure it Disappears After Completion

• Use an Opacity animation at the end of the scroll effect to gradually fade out the animation after it completes.
• Alternatively, set the wrapper div to display: none after reaching the desired point.

Summary

This method keeps your Lottie animation fixed in place while scrolling and ensures it completes in a controlled timeframe without manual timing adjustments. By fine-tuning the scroll interaction percentages, you can define exactly when the animation ends.
