How to build a pop-up modal in Webflow

The tutorial provides a detailed guide on creating a user-initiated popup modal with a focus on styling and interactions. It starts by instructing the user to add headline text and a button with specific styling such as centered text alignment and a gradient background. A div is then added to contain the modal, styled with a fixed position and a high z-index to ensure it appears above other elements. The signup form inside the modal is styled with padding, a white background, and a drop shadow for depth. Input fields and a form button are styled for consistency, and a close button is added for functionality. The tutorial concludes with instructions on setting up interactions to ensure the modal is invisible on page load, using animations for scale, rotation, and opacity to create a seamless user experience when the modal is activated.
