<script type="text/babel">
    class Abox extends React.Component{
        constructor(props) {
        super(props);
       
    }
    render() {
        return (
            <div className="box1">
                {
                    this.props.children
                }
            </div>
        )
    }

    ReactDOM.render(
        <div className="box1">
            <Abox>
