React Aria Components<\/a><\/strong> gives you a library of accessible, headless UI components that work across mouse, touch, and keyboard. But being headless means they ship with zero styles and zero animations by default. Your popovers just appear. Your modals snap open. No transitions, no easing, no polish.<\/p>\n

That\u2019s fine if you\u2019re building an internal tool. But probably less fine if you\u2019re shipping a customer-facing product where smooth motion signals quality.<\/p>\n

\n \"React\n <\/figure>\n

The good news is that React Aria provides clear paths for adding animation, and they cover everything from a simple CSS fade to physics-based animations.<\/p>\n

Let\u2019s take a look.<\/p>\n

CSS transitions with data states<\/h2>\n

The simplest path requires zero JavaScript animation libraries. React Aria overlay components like Popover<\/code>, Modal<\/code>, ModalOverlay<\/code>, Tray<\/code>, and Menu<\/code> expose [data-entering]<\/code> and [data-exiting]<\/code> states.<\/p>\n

These data attributes are applied automatically when the component mounts or unmounts, and the component waits for your exit animations to finish before removing itself from the DOM.<\/p>\n

\r\n.react-aria-Popover {\r\n  transition: opacity 200ms, translate 200ms;\r\n}\r\n\r\n.react-aria-Popover[data-entering],\r\n.react-aria-Popover[data-exiting] {\r\n  opacity: 0;\r\n  translate: 0 -8px;\r\n}\r\n<\/pre>\n
With that CSS, your Popover fades in and slides down 8 pixels on open, then reverses on close. The browser handles the timing. No JavaScript animation overhead, no extra dependencies.<\/p>\n
This works for any component that mounts conditionally. The data-exiting<\/code> attribute is especially important: without it, the component would be removed from the DOM instantly and you\u2019d never see the exit animation. React Aria handles the timing for you, keeping the element alive until the transition completes.<\/p>\n
Try the code below.<\/p>\n
