Can the background shadow animation shown on the Build microinteractions around mouse movement example on the Webflow Interaction feature page be achieved using just interactions or does it require custom code?

The background shadow animation in the Build microinteractions around mouse movement example can be achieved using Webflow's native interactions feature, but may require some custom code for more advanced effects.

​

1. Create the Element and Shadow

• Add a div block in your Webflow project to act as the background element.
• Style the div with an initial box shadow to give it a starting point for the interaction.

​

2. Set Up Mouse Move Interaction

• Select the div block, and go to the Interactions panel in Webflow.
• Choose the Element Trigger, then click on Mouse Move.
• Define initial and target conditions for the mouse movement in the interaction settings. You’ll set how the shadow's properties should change in response to pointer movement.

​

3. Configure Shadow Dynamics

• Add actions within the mouse move interaction to adjust properties like the shadow's offset and blur according to the pointer's position.
• Tailor the easing and speed settings for smooth transitions that match your design intent.

​

4. Custom Code for Advanced Effects

• If Webflow’s interactions don't offer the precision needed (for example, more dynamic shadow responses), you may need to add custom code. Incorporate JavaScript to calculate and adjust shadow properties based on precise mouse movement data.

​

Summary

The basic background shadow animation around mouse movement can be achieved through Webflow’s interaction panel. However, for more detailed effects, consider using a small amount of custom JavaScript. Always test interactions thoroughly to ensure performance and visual expectations are met.
