To achieve a smooth darkening effect on an image when a modal window is overlaid during scrolling in Webflow, you can follow these steps:

  1. Create a modal window: Start by creating a modal window using the Webflow Designer. You can use the built-in modal component or create a custom one using interactions.

  2. Style the modal: Customize the appearance of the modal window by adjusting its position, size, and styling to fit your design requirements.

  3. Overlay the modal window: Set the modal window to have a higher z-index than the other content on the page so that it appears on top when triggered. You can use the "Position" and "Z-Index" settings in the Style tab to achieve this effect.

  4. Add a background overlay: To create the darkening effect on the image behind the modal, you can add a background overlay. You can do this by adding a new div element as a child of the modal window, giving it absolute positioning with 100% width and height, and setting its background color to a semi-transparent black.

  5. Set up interactions: Use Webflow interactions to create the smooth darkening effect when the modal is triggered. Start by creating an interaction that animates the opacity of the background overlay from 0 (fully transparent) to a desired value (e.g., 0.6) within a specified duration (e.g., 0.3 seconds). Apply this interaction to the background overlay element.

  6. Trigger the modal: Set up a trigger for the modal to open when a specific action occurs, such as clicking on an image or a button. You can use the Interactions panel to create a trigger and define the action that opens the modal.

  7. Enable scrolling: By default, when a modal is open in Webflow, scrolling on the page is disabled to prevent users from interacting with content behind the modal. However, if you want scrolling to be enabled while the modal is open, you can add a custom code snippet to override this behavior. Add the following code to the <head> section of your page's custom code:

<style>  html, body {    overflow: visible !important;  }</style>

This will ensure that users can scroll through the page's content even when the modal is open.

By following these steps, you can achieve a smooth darkening effect on an image when a modal window is overlaid during scrolling in Webflow. Remember to customize the design and timing of the effect to match your specific requirements.
