Avoid using multiple modals—it's a surefire way to overwhelm and potentially stress out your users. Stacked modals require users to dismiss each overlay one by one, creating a tedious and anxiety-inducing experience. Furthermore, layering modals obscures the main content and can create confusion, making users think they've navigated away from the main window.

This not only interrupts their workflow but also distracts from the content or tasks they were initially focused on. Simply put, multiple modals are more likely to frustrate users than facilitate their experience. Stick to a single, well-designed modal to keep things clean and user-friendly.
