It's built upon the\n * [`Transition`](https://reactcommunity.org/react-transition-group/transition)\n * component, so it inherits all of its props.\n *\n * `CSSTransition` applies a pair of class names during the `appear`, `enter`,\n * and `exit` states of the transition. The first class is applied and then a\n * second `*-active` class in order to activate the CSS transition. After the\n * transition, matching `*-done` class names are applied to persist the\n * transition state.\n *\n * ```jsx\n * function App() {\n * const [inProp, setInProp] = useState(false);\n * return (\n *
