display: none vs CSS opacity
Developers should use display: none when they need to hide elements entirely from the user interface, such as in responsive design to hide non-essential content on mobile devices, or in interactive features like tabs or modals where content is shown conditionally meets developers should use css opacity to create smooth transitions, modal overlays, or hide/show elements without removing them from the dom, which is essential for animations and user interface enhancements. Here's our take.
