当屏幕尺寸低于 1400 像素时，此附加 CSS 代码将创建一个移动切换按钮汉堡。您需要为移动导航菜单添加 html 代码和 css 以及几行 javascript 以使切换也能正常工作。

.navBar{
    display: flex;
    justify-content: space-between;
    align-items: center;
    background-color: #91CEC9;
    color: #FFF;    
}

.navbarLinks ul{
    margin: 0;
    padding: 0;
    display: flex;
}

.navbarLinks li{
    list-style: none;
}

.navbarLinks li a{
    text-decoration: none;
    color: #FFF;
    padding: 42px;
    display: block;
    font-size: 20px;
}

.navbarLinks li a:hover{
    background-color: #163640;
}
