js代碼:

const left = document.querySelector('.left');
//打印,檢測是否獲取DOM元素;
console.log(left);

const right = document.querySelector('.right');
const container = document.querySelector('.container');


left.addEventListener('mouseenter', () => {
    container.classList.add('hover-left')
})


left.addEventListener('mouseleave', () => {
    container.classList.remove('hover-left')
})


right.addEventListener('mouseenter', () => {

    container.classList.add('hover-right')
})


right.addEventListener('mouseleave', () => {
    container.classList.remove('hover-right')
