我有一个块，有一个属性“溢出：滚动”我想改变我的滚动高度从https://ibb.co/gFyfDwT到这个https://ibb.co/SsByRXB

Lesson.jsx

import React from 'react';
import less from "./css/lesson.module.css";
import "./css/betaLesson.css";

export class Lessons extends React.Component {

    render() {
        return (
            <>
                <div className="abc">
                    <div className={less.wrapper}>
                        <div>
                            <div className={less.sidebar}>
                                <div>
                                    {listLessons}
                                </div>
                            </div>
                        </div>
                    </div>
                </div>
            </>
        );
    }
}
