If the first item in your Webflow sticky horizontal scroll is starting to move to the left earlier than intended, there could be a few potential causes to look into:
1. CSS positioning: Make sure that the position of your first item is set correctly. For elements within a horizontal scroll, it's common to use a combination of `display: flex` and `overflow-x: scroll` on the parent container, and `display: inline-block` or `float: left` on the child items. If the positioning properties are not set correctly, it can lead to unexpected behavior.
2. Element width and margin: Check the width and margin settings of your first item. If the width is set too large or there is excessive margin, it could cause the item to start moving to the left earlier than intended. Be sure to adjust the dimensions and positioning properties to ensure that the item fits within the scroll container properly.
3. Scroll behavior settings: Check if there are any custom interactions or scroll-related settings applied to the scroll container or the first item. For example, if you have set a custom scroll interaction that affects the position or animation of the items, it could cause the first item to start moving earlier. Review your interactions and make sure they are working as intended.
4. Negative margins or padding: If you have applied negative margins or padding to the first item or any of its parent elements, it can affect the positioning and movement within the sticky horizontal scroll. Ensure that there are no negative values set for margins or padding that could be causing the issue.
5. JavaScript conflicts: If you have any custom JavaScript code implemented on your page, it's possible that there might be a conflict causing the first item to move incorrectly. Check the console for any JavaScript errors and review your code to see if there are any conflicting scripts affecting the scroll behavior.
By investigating these potential causes, you should be able to identify the reason why the first item in your Webflow sticky horizontal scroll is starting to move to the left earlier than intended and make the necessary adjustments to resolve the issue.
