如何将React (第三方库和css一起)添加到html网站？

<script src="https://cdn.jsdelivr.net/npm/react@17.0.2/umd/react.development.js"></script>
<script src="https://cdn.jsdelivr.net/npm/react-dom@17.0.2/umd/react-dom.development.js"></script>
<script src="https://cdn.jsdelivr.net/npm/babel-standalone@6.26.0/babel.min.js"></script>

<div id="root"></div>

<script type="text/babel">
  // React组件代码
  class MyComponent extends React.Component {
    render() {
      return (
        <div>
          <h1>Hello, React!</h1>
        </div>
      );
    }
  }

  // 渲染React组件
  ReactDOM.render(<MyComponent />, document.getElementById('root'));
</script>

<style>
  /* CSS样式代码 */
  h1 {
    color: blue;
  }
</style>
