I created a modal window (carefully following Matt Vogel's 'How to create a pop-up modal in Webflow').
The modal appears in the editor, but after I publish and then click to open the modal, the opaque background appears, but the modal and its contents don't.
In the editor, go to the 'Science' page. Then preview and click the first grey 'Details' link to open the modal.
Please let me know if you're able to figure out what I'm doing wrong.
