How can I fix the issue of the percentage of my Lottie animation not being consistent between mobile and desktop versions in Webflow?

Inconsistent Lottie animation percentage progression across mobile and desktop is usually caused by differences in scroll behavior, element sizing, or trigger settings between breakpoints.

1. Check Trigger Type and Scroll Settings

• Ensure you are using the "While scrolling in view" trigger on the Lottie animation.
• This trigger calculates animation progress based on the visible portion of the element in the viewport, which can vary significantly between desktop and mobile due to screen sizes.
• Animations driven by page scroll ("While page is scrolling") will behave differently as page height changes between breakpoints.

2. Use a Fixed Height for the Animation Container

• Wrap your Lottie animation in a div block with a fixed height (e.g., 100vh or a set number of pixels).
• Assign the same height across breakpoints to normalize scroll behavior.
• This prevents the percentage trigger from misfiring due to variable element heights.

3. Ensure Consistent Offset Settings

• In the interaction settings, check the Start and End offsets of your scroll animation.
• These percentages are based on the viewport and element height — if they're different on desktop and mobile, animations will play at different scroll speeds or ranges.
• Set the same offsets across all breakpoints for consistency.

4. Optimize the Animation for Viewport

• Resize or reposition the animation for each breakpoint using style settings, but avoid drastically altering its bounding box size, which affects trigger accuracy.
• If using Lottie as a background or decorative element, consider decoupling it from scroll animation and using timed animations instead on mobile.

5. Preview and Test Each Breakpoint

• Webflow interactions behave differently on each breakpoint, especially if elements shift layout.
• Use Webflow’s built-in preview mode and toggle between breakpoints to test animation smoothness.

6. Fallback: Duplication by Breakpoint

• If precise synchronization isn't achievable, you can duplicate the animation:
• Create separate Lottie elements for desktop and mobile.
• Use visibility settings (display: none/block) to show the proper version per device.
• Apply slightly different interaction settings optimized for each layout.

Summary

To fix Lottie animation inconsistency across devices, use consistent offsets, maintain equal container sizing, and standardize the scroll trigger type. For best control, wrap your Lottie in a fixed-height container and validate behavior in preview mode across breakpoints.
