我的问题是关于当您将鼠标悬停在"打开按钮上时滑入的菜单"它推动了一切,这是一个问题。它旨在打开图像,我无法弄清楚如何做到这一点。我曾经尝试过添加花车和改变位置标签之类的东西,似乎没有任何效果。这是我的代码:



html,
body {
    width: 100%;
    height: 100%;
    margin: 0px;
    padding: 0px;
    overflow-x: hidden;
}

#Bar {
    position: relative;
    top: 0;
    left: 0;
    width: 100%;
    height: 64px;
    background-color: #592881
}

#logo {
    position: relative;
    top: -40px;
    text-align: center;
    left: 0;
    right: 0;
    z-index: 1;
}

.sidenav {
    height: 100%;
    width: 0;
    position: fixed;
    z-index: 1;
    top: 100px;
    left: 0;
    background: rgba(89, 40, 129, .7);
    overflow-x: hidden;
    transition: 0.5s;
    padding-top: 60px;
    text-align: center;
}

.sidenav a {
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 25px;
    color: black;
    display: block;
    transition: 0.3s;
    position: static;
}

.sidenav a:hover {
    color: grey;
}

.sidenav .closebtn {
    position: absolute;
    top: 0;
    right: 25px;
    font-size: 36px;
    margin-left: 50px;
}

@media screen and (max-height: 450px) {
    .sidenav {
        padding-top: 15px;
    }
    .sidenav a {
        font-size: 18px;
    }
}

.fade {
