How can I prevent the home page from scrolling when a modal is open in Webflow, and ensure that the modal always opens at the top of the page?

To prevent the home page from scrolling when a modal is open in Webflow and ensure that the modal always opens at the top of the page, you can follow these steps:

1. Create a section or a div element that wraps around your modal content. Let's call this element "modal-wrapper".

2. Give the "modal-wrapper" element a position of fixed and set its top, left, right, and bottom values to 0. This will make it cover the entire viewport and stay fixed in place.

3. Inside the "modal-wrapper" element, create another div element to hold your modal content. You can call this element "modal-content".

4. Apply the necessary styling to the "modal-content" element to position it at the top center of the viewport. You can use Flexbox or CSS Grid to achieve this. For example, you can set its display to flex, justify-content to center, and align-items to flex-start.

5. Style the "modal-content" element to have a fixed height and set its overflow-y property to auto. This will create a scrollable area within the modal if its content exceeds the height of the viewport.

6. Add your modal content, such as text, images, or form elements, within the "modal-content" element.

7. Finally, make the modal hidden by default. You can either set the initial state of the "modal-wrapper" element to display: none or set its opacity to 0 and use Webflow's interactions or custom code to show/hide the modal.

By following these steps, the "modal-wrapper" element will overlay the home page, preventing it from scrolling when the modal is open. Additionally, the modal will always open at the top of the page, providing a consistent user experience.
