如何在react.js中正确制作动画/过渡

import React, { useState } from 'react';
import './App.css'; // 确保导入CSS

function App() {
  const [toggle, setToggle] = useState(false);

  return (
    <div>
      <button onClick={() => setToggle(!toggle)}>Toggle</button>
      <div className={`box ${toggle ? 'active' : ''}`}>
        This is a box
      </div>
    </div>
  );
}

export default App;

.box {
  width: 100px;
  height: 100px;
  background-color: blue;
  transition: transform 0.5s ease;
}

.box.active {
  transform: translateX(100px);
}

@keyframes example {
  from { background-color: red; }
  to { background-color: yellow; }
}

.box {
  width: 100px;
  height: 100px;
  animation-name: example;
  animation-duration: 2s;
}

import React from 'react';
import './App.css';

function App() {
  return <div className="box">This is a box</div>;
}

export default App;

npm install framer-motion

import { motion } from 'framer-motion';

function App() {
  return (
    <motion.div
      animate={{ scale: 2 }}
      transition={{ duration: 0.5 }}
    >
      This is a box
    </motion.div>
  );
}

export default App;

npm install react-transition-group

import { CSSTransition } from 'react-transition-group';
import './App.css';

function App() {
  const [inProp, setInProp] = useState(false);
  return (
    <div>
      <CSSTransition in={inProp} timeout={500} classNames="my-node">
        <div>
          {"I'll receive my-node-* classes"}
        </div>
      </CSSTransition>
      <button onClick={() => setInProp(!inProp)}>
        Click to Enter
      </button>
    </div>
  );
}

export default App;

.my-node-enter {
  opacity: 0;
}
.my-node-enter-active {
  opacity: 1;
  transition: opacity 500ms ease-in;
}
.my-node-exit {
  opacity: 1;
}
.my-node-exit-active {
  opacity: 0;
  transition: opacity 500ms ease-in;
}
