我现在面临的主要问题是，当我试图点击汉堡包菜单时，边栏消失了。我找不到代码有什么问题。

该部分的代码出现在这里。这是我在创建导航栏和侧栏之后创建的唯一一个部分

function togglesideBar(ref) {

}

此代码用于我的部分中的动画标题。我使用了javascript Typed.js库

window.onload = function() {
    console.log("loaded")
    var typed = new Typed('#typed', {
        strings: ["Welcome to Sanan.com", "Learn Web Development", "Learn App development", "Learn Facebook Ads", "and other awesome programming concepts with me :)"],
        backSpeed: 15,
        smartBackspace: true,
        backDelay: 1200,
        startDelay: 1000,
        typeSpeed: 25,
        loop: true,
    });
}

添加到

.sideBar

，如下所示：

.sideBar {
    position: absolute;
    top: 0px;
    left: -200px;
    width: 200px;
    height: 100%;
    background: black;
    transition: all 300ms linear;
    z-index: 9999;
}
