- What is the difference between using opacity: 0 and visibility: hidden?
- When using opacity:0, the elements are transparent but still occupy space, interactable, and support transition animation; when using visibility:hidden, the elements are not visible but still occupy space, but do not respond to interaction, and child elements can override this setting. Neither element is removed from the layout, but the behavior and applicable scenarios are different: 1. opacity:0 maintains functionality and animation capabilities; 2. visibility:hidden blocks interaction and allows child elements to be displayed; 3. Transition animation can be used on opacity, but cannot be used for visibility; 4. Screen readers may still read these two hidden elements, and other methods should be used if they need to be completely hidden.
