What could be causing the first item in my Webflow sticky horizontal scroll to start moving to the left earlier than intended?

If the first item in your Webflow sticky horizontal scroll moves to the left earlier than intended, it’s likely caused by setup issues related to sticky positioning, transform settings, or incorrect scroll distances.

1. Check Sticky Container and Parent Structure

• Ensure the sticky section is inside a properly sized parent that uses the correct overflow settings.
• The parent container needs to have overflow: hidden (or auto, depending on the effect) and must be taller than the sticky element’s height.
• For horizontal scrolling via sticky behavior, the sticky child should typically be set to position: sticky with top: 0, and the parent must be tall enough to allow vertical scrolling.

2. Verify Width of Scrolling Content

• The horizontally scrollable container (e.g., the items wrapper) must be wider than the viewport, or the sticky pivot won’t have enough distance to work correctly.
• Make sure the total width of the scroll track (all horizontal items combined) is correctly defined—usually set in pixels or with flex layout and width: 100vw per item.

3. Match Scroll Duration and Animation Distance

• If you’re using Webflow interactions (e.g., while page is scrolling), your animation may be triggering or starting too early.
• Check the scroll trigger’s start and end points, and ensure the animation offset or duration matches the expected scroll range.
• Try adjusting the “Scroll action starts when element enters viewport” setting to start later (e.g., 25% instead of 0%).

4. Double-Check Transform Moves

• Look at the animation settings for the horizontal scroll. The motion might be programmed to begin before the sticky effect fully kicks in.
• If your “Move” interaction is bound to the scroll progress, test adjusting the scroll progress range (e.g., 0%–100%) to align with the desired behavior.

5. Avoid Unexpected Margins or Padding

• Check for any left margin, padding, or offset on the first item that might cause it to appear like it's moving prematurely.
• Reset and test with no margins to rule this out.

6. Test on Different Viewports

• Responsive issues (like percentage-based widths on nested containers) can cause the scroll start to misalign on some screen sizes.
• Use Webflow’s Designer view and adjust breakpoints to test if the issue is viewport-specific.

Summary

The first item in your sticky horizontal section might be moving early due to misaligned scroll triggers, incorrect content width, or early-starting interactions. Double-check sticky positioning, scroll animation timing, and container width to ensure smooth behavior.
