What could be causing the smooth background fades between sections to not transition in Interactions 2.0 in Webflow, even after recreating them as they were in Interactions 1.0?

If your smooth background fades between sections are not working in Webflow Interactions 2.0, even after recreating them from Interactions 1.0, there are a few possible causes.

1. Ensure the Correct Elements are Targeted

• Check the structure of your elements. If you've rebuilt the interactions, ensure you're selecting the correct elements in the "Affect" dropdown within the interaction panel.
• Verify that the background layer or parent container is the one being modified, not an unintended child element.

2. Use Opacity or Background Color Changes Correctly

• If you're using opacity, make sure the background is in a separate, absolutely positioned div that overlaps the section.
• If you're changing the background color of the section itself, instead of opacity, ensure that background transitions are enabled in CSS (Style Panel > Transitions).

3. Check Interaction Triggers

• Webflow’s Interactions 2.0 operates differently from 1.0, so ensure that the trigger is correctly set (e.g., “While scrolling in view” rather than “Scroll into view” if you need gradual fading).
• If using page trigger interactions, be sure they are active, and not just applied to a single element.

4. Verify Timing and Animation Curves

• Check duration and easing settings. If your animation duration is too short or easing is too abrupt, it may not be visible.
• Use smooth easing types like “Ease” or “Ease In-Out” instead of “Linear” for smoother transitions.

5. Test Z-Index and Layering Issues

• If you’re fading in/out a layered background div, ensure it has a higher z-index compared to section content.
• If another element is positioned in front of the background, it may block visibility of the transition.

6. Browser and Rendering Issues

• Test in another browser to rule out rendering glitches.
• Clear Webflow’s cache and republish the site if changes do not appear as expected.

Summary

Ensure that the correct elements are being targeted, transitions are applied to the right properties (opacity or background color), interaction triggers are properly set, and that timing, easing, and layering are causing no conflicts. Testing in multiple browsers and republishing can also help resolve unexpected behavior.
